Jihad


Islam is surrounded by many stereotypes, such as that Islam is a terrorist religion, and that Jihad is terrorism. But the truth is that Islam does not support any action of terrorism for any reason.

Jihad
Jihad is an Arabic word that means struggle, resisting, or striving, and it does not mean “fight” or “war”. There are two different types of jihad. The first type of jihad is the greater jihad which an inner spiritual struggle.

Spiritual struggle
Prophet Muhammad explained this type of jihad when he told his companions after a war:
"رجعنا من الجهاد الأصغر إلى الجهاد الأكبر. قالوا: وما الجهاد الأكبر؟ قال: جهاد النفس
“We came from the lesser jihad to the greater jihad”. They asked him: “What is the greater jihad?” He said: “The struggle against oneself”.

All humans enjoy worldly pleasures and desire a nice and comfortable life. These desires are normal, but the problem is only when you follow them unquestioningly as they are a god. That is the trial... the test of our life. With patience, we can pass this trial and test. The greater jihad is to learn patience and self-control, and is to manage your desires, emotions, and conflicts, instead of letting your desires lead you as an animal. By this type of jihad you can clean your inner soul and transfer it from the soul that is prone to evil to be reassured soul. Fasting is very good tool that can help you in your inner spiritual struggle, because you desire the food but you wait until the time God make it for you to eat. Therefore, the prophet Muhammad considered the worship is Jihad. In addition, most worship need a struggle to be performed.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا خَالِدٌ، حَدَّثَنَا حَبِيبُ بْنُ أَبِي عَمْرَةَ، عَنْ عَائِشَةَ بِنْتِ طَلْحَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّهَا قَالَتْ يَا رَسُولَ اللَّهِ تُرَى الْجِهَادَ أَفْضَلَ الْعَمَلِ، أَفَلاَ نُجَاهِدُ قَالَ ‏ "‏ لَكِنَّ أَفْضَلَ الْجِهَادِ حَجٌّ مَبْرُورٌ ‏"‏‏.
Narrated `Aisha:
(That she said), "O Allah's Messenger ()! We consider Jihad as the best deed. Should we not fight in Allah's Cause?" He said, "The best Jihad (for women) is Hajj-Mabrur (i.e. Hajj which is done according to the Prophet's tradition and is accepted by Allah).

In-book reference                              : Book 56, Hadith 3

Physical struggle
The second type of jihad is the lesser jihad, which is an outer physical struggle against the enemies of Islam, which may take a violent (war) or non-violent form (advice). So Islam considers your struggle against your soul is greater than your struggle against your enemies!
Prophet Muhammad explained the non-violent jihad when he said:
عَنْ طَارِقِ بْنِ شِهَابٍ، أَنَّ رَجُلاً، سَأَلَ النَّبِيَّ صلى الله عليه وسلم وَقَدْ وَضَعَ رِجْلَهُ فِي الْغَرْزِ أَىُّ الْجِهَادِ أَفْضَلُ قَالَ " كَلِمَةُ حَقٍّ عِنْدَ سُلْطَانٍ جَائِرٍ
a man asked the Prophet, when he had put his leg in the stirrup: "Which kind of Jihad is best?'" He said: "a word of truth spoken before an unjust ruler."
A word of truth in front of a tyrannical ruler.”
“The just word against an unjust ruler”
The word of justice in front of the oppressive ruler”. 
Grade: Hasan (Darussalam)  - Reference  : Sunan an-Nasa'i 4209

Islam does not accept oppression, it does not support dictatorship, and it require Muslims to have a duty of accounting the ruler. It is a sin when you wrong yourself and accept the oppression and living without any quality or right life like animals, so if you have weakness and you cannot fight for your life, Quran encourages you to move to another land where you can have a better life as the human that God honor.
Violent jihad is the fight in the war that is conducted by a government, and Qur'an stipulates one condition for it. It is to defend yourself, not to attack or assault anyone.
وَقَاتِلُوا فِي سَبِيلِ اللَّهِ الَّذِينَ يُقَاتِلُونَكُمْ وَلَا تَعْتَدُوا ۚ إِنَّ اللَّهَ لَا يُحِبُّ الْمُعْتَدِينَ . وَاقْتُلُوهُمْ حَيْثُ ثَقِفْتُمُوهُمْ وَأَخْرِجُوهُم مِّنْ حَيْثُ أَخْرَجُوكُمْ ۚ وَالْفِتْنَةُ أَشَدُّ مِنَ الْقَتْلِ ۚ وَلَا تُقَاتِلُوهُمْ عِندَ الْمَسْجِدِ الْحَرَامِ حَتَّىٰ يُقَاتِلُوكُمْ فِيهِ ۖ فَإِن قَاتَلُوكُمْ فَاقْتُلُوهُمْ ۗ كَذَٰلِكَ جَزَاءُ الْكَافِرِينَ . فَإِنِ انتَهَوْا فَإِنَّ اللَّهَ غَفُورٌ رَّحِيمٌ . وَقَاتِلُوهُمْ حَتَّىٰ لَا تَكُونَ فِتْنَةٌ وَيَكُونَ الدِّينُ لِلَّهِ ۖ فَإِنِ انتَهَوْا فَلَا عُدْوَانَ إِلَّا عَلَى الظَّالِمِينَ
Fight in the way of God those who fight you but do not assault. Indeed. God does not like the assaulters.
And kill them wherever you overtake them and expel them from wherever they have expelled you, and fitnah is worse than killing. And do not fight them at al-Masjid al- Haram until they fight you there. But if they fight you, then kill them. Such is the recompense of the disbelievers.
And if they cease, then indeed, Allah is Forgiving and Merciful.
Fight them until there is no [more] fitnah and [until] worship is [acknowledged to be] for Allah. But if they cease, then there is to be no aggression except against the oppressors. (2:190-193)

Jihad
Greater jihad
Lesser jihad
The struggle against oneself.
Non-violent
Violent
The word of justice in front of the oppressive ruler.
To defend, not to attack.

Legitimacy of war 
The only valid basis for military jihad is to end oppression when all other measures have failed. The original violent jihad was permission to fight back against those who broke their pledges. Thus the Qur'an justified defensive jihad by allowing Muslims to fight back against hostile and dangerous forces.
According to the majority of jurists, the Qur'anic casus belli (justification of war) are restricted to aggression against Muslims and persecution of Muslims because of their religious belief.
They hold that unbelief in itself is not the justification for war. Yes, it is one of the greatest sins, it is between the individual and his God the Almighty and the punishment for this sin is to be postponed to the Hereafter. Muslims cannot wage war for propagation or implementation of Islam. How can Muslims make war on the account of a nation's religion if Quran states freedom of religion very clear?
لَا إِكْرَاهَ فِي الدِّينِ ۖ قَد تَّبَيَّنَ الرُّشْدُ مِنَ الْغَيِّ
There shall be no compulsion in [acceptance of] the religion. The right course has become clear from the wrong.  (2:256) 

Plus, Quran distinguished between the non-Muslims who fights Muslims and the non-Muslims who do not fight Muslims. Muslims have to fight the first one back, but they are not forbidden from the second one to be righteous and acting justly toward them.
لَّا يَنْهَاكُمُ اللَّهُ عَنِ الَّذِينَ لَمْ يُقَاتِلُوكُمْ فِي الدِّينِ وَلَمْ يُخْرِجُوكُم مِّن دِيَارِكُمْ أَن تَبَرُّوهُمْ وَتُقْسِطُوا إِلَيْهِمْ ۚ إِنَّ اللَّهَ يُحِبُّ الْمُقْسِطِينَ .Sahih InternationalAllah does not forbid you from those who do not fight you because of religion and do not expel you from your homes - from being righteous toward them and acting justly toward them. Indeed, Allah loves those who act justly.Yusuf AliAllah forbids you not, with regard to those who fight you not for (your) Faith nor drive you out of your homes, from dealing kindly and justly with them: for Allah loveth those who are just. إِنَّمَا يَنْهَاكُمُ اللَّهُ عَنِ الَّذِينَ قَاتَلُوكُمْ فِي الدِّينِ وَأَخْرَجُوكُم مِّن دِيَارِكُمْ وَظَاهَرُوا عَلَىٰ إِخْرَاجِكُمْ أَن تَوَلَّوْهُمْ ۚ وَمَن يَتَوَلَّهُمْ فَأُولَٰئِكَ هُمُ الظَّالِمُونَ
Sahih International
Allah only forbids you from those who fight you because of religion and expel you from your homes and aid in your expulsion - [forbids] that you make allies of them. And whoever makes allies of them, then it is those who are the wrongdoers.
Yusuf Ali
Allah only forbids you, with regard to those who fight you for (your) Faith, and drive you out of your homes, and support (others) in driving you out, from turning to them (for friendship and protection). It is such as turn to them (in these circumstances), that do wrong.
God does not forbid you from those who do not fight you because of religion and do not expel you from your homes - from being righteous toward them and acting justly toward them. Indeed, God loves those who act justly. God only forbids you from those who fight you because of religion and expel you from your homes and aid in your expulsion - [forbids] that you make allies of them. And whoever makes allies of them, then it is those who are the wrongdoers.” (60:8-9)

Fighting in self-defense is not only legitimate but considered obligatory upon Muslims, according to the Qur'an.
كُتِبَ عَلَيْكُمُ الْقِتَالُ وَهُوَ كُرْهٌ لَّكُمْ ۖ وَعَسَىٰ أَن تَكْرَهُوا شَيْئًا وَهُوَ خَيْرٌ لَّكُمْ ۖ وَعَسَىٰ أَن تُحِبُّوا شَيْئًا وَهُوَ شَرٌّ لَّكُمْ ۗ وَاللَّهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ
Fighting has been enjoined upon you while it is hateful to you. But perhaps you hate a thing and it is good for you; and perhaps you love a thing and it is bad for you. And Allah Knows, while you know not. (2:216)

The Qur'an says that if the hostile behavior of the enemy ceases, the reason of the war lapses.
فَإِنِ انتَهَوْا فَلَا عُدْوَانَ إِلَّا عَلَى الظَّالِمِينَ
But if they cease, then there is to be no aggression except against the oppressors. (2:190-193)

Yes, there were some offensive wars, not defensive, in the Islamic history. These types of wars were political conflict, not religious. Plus, the sources of Islam are Quran and the prophet’s traditions. But Islamic history is not one of these sources.
Why did God not allowed Muslims to even defend themselves in Mecca or fight the disbelievers who persecuted them for their religion? But He allowed them to do it when they were in Madinah? Actually, because they were too weak in Mecca to defend themselves, but they gain more power in Madinah, so they can defend themselves. Therefore, some scholars argue that war may only be legitimate if Muslims have at least half the power of the enemy and thus capable of winning it.
So Muslims need to prepare themselves before they call for jihad. Without this preparation, they just kill themselves.
وَأَعِدُّوا لَهُم مَّا اسْتَطَعْتُم مِّن قُوَّةٍ وَمِن رِّبَاطِ الْخَيْلِ تُرْهِبُونَ بِهِ عَدُوَّ اللَّهِ وَعَدُوَّكُمْ وَآخَرِينَ مِن دُونِهِمْ لَا تَعْلَمُونَهُمُ اللَّهُ يَعْلَمُهُمْ ۚ وَمَا تُنفِقُوا مِن شَيْءٍ فِي سَبِيلِ اللَّهِ يُوَفَّ إِلَيْكُمْ وَأَنتُمْ لَا تُظْلَمُونَ
And prepare against them whatever you are able of power and of steeds of war by which you may terrify the enemy of Allah and your enemy and others besides them whom you do not know [but] whom Allah knows. And whatever you spend in the cause of Allah will be fully repaid to you, and you will not be wronged. (8:60)

As you read last verse, the goal of this preparation is to attack or even fight. It is to deter the enemy of attacking us. So it is to avoid the war.

Ethics of warfare
However, even in the war, Muslims have to commit to Islamic moral rules, such as the rule: "Do not fight whom did not fight"; because Qur'an said "No bearer of burdens will bear the burden of another.”(35:18) When the Muslims were defeated in the battle of Uhud the prophet Muhammad accepted the defeat as a lesson to teach Muslims for next battle, but he did not send them to Mecca to sneak its people or burn their houses.
During his life, Prophet Muhammad gave various injunctions to his forces and adopted practices toward the conduct of war, such as this injunction.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، عَنْ سُفْيَانَ، عَنْ أَبِي الزِّنَادِ، عَنِ الْمُرَقَّعِ بْنِ عَبْدِ اللَّهِ بْنِ صَيْفِيٍّ، عَنْ حَنْظَلَةَ الْكَاتِبِ، قَالَ غَزَوْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَمَرَرْنَا عَلَى امْرَأَةٍ مَقْتُولَةٍ قَدِ اجْتَمَعَ عَلَيْهَا النَّاسُ فَأَفْرَجُوا لَهُ فَقَالَ ‏(‏مَا كَانَتْ هَذِهِ تُقَاتِلُ فِيمَنْ يُقَاتِلُ‏) .‏ ثُمَّ قَالَ لِرَجُلٍ ‏(‏انْطَلِقْ إِلَى خَالِدِ بْنِ الْوَلِيدِ فَقُلْ لَهُ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم يَأْمُرُكَ يَقُولُ لاَ تَقْتُلَنَّ ذُرِّيَّةً وَلاَ عَسِيفًا‏)‏‏.
It was narrated that Hanzalah Al-Katib said:
“We went out to fight alongside the Messenger of Allah (), and we passed by a slain woman whom the people had gathered around. They parted (to let the Prophet () through) and he said: ‘This (woman) was not one of those who were fighting.’ Then he said to a man: ‘Go to Khalid bin Walid and tell him that the Messenger of Allah () commands you: “Do not kill any women or any (farm) laborer.’”
Grade    : Sahih (Darussalam)                         
English reference         : Vol. 4, Book 24, Hadith 2842
Arabic reference           : Book 24, Hadith 2949

The most important of these injunctions were summarized by Muhammad's companion and first Caliph, Abu Bakr, in the form of ten rules for the Muslim army.
O people! I charge you with ten rules; learn them well!
Stop, O people, that I may give you ten rules for your guidance in the battlefield.
Do not commit treachery or deviate from the right path.
You must not mutilate dead bodies.
Neither kill a child, nor a woman, nor an aged man.
Bring no harm to the trees, nor burn them with fire, especially those which are fruitful.
Slay not any of the enemy's flock, save for your food.
You are likely to pass by people who have devoted their lives to monastic services; leave them alone.

Under the Islamic jurisprudence, the following acts are illegal and not permissible in wars:
-          Surprise attacks. The Qur'an commands Muslims to make a proper declaration of war prior to the commencement of military operations.
-          Burning or drowning the enemy
-          The mutilation of dead bodies.
-          Displaying pomp and unnecessary boasting.
-          Employ weapons that cause unnecessary injury to the enemy, such as poisonous spears.
-          Kill women or children unless they are fighting against the Muslims.
-          Killing of those who are not able to fight, including monks, farmers, and serfs, as well as mentally and physically disabled.
-          Harming civilian areas and pillaging residential areas
-          The destruction of trees, crops, livestock and farmlands.
-          Loot travelers.
-          Use the local facilities of the native people without their consent.
In addition, Islam does not permit Muslims to reject peace and continue bloodshed, since God said:
وَإِن جَنَحُوا لِلسَّلْمِ فَاجْنَحْ لَهَا وَتَوَكَّلْ عَلَى اللَّهِ ۚ إِنَّهُ هُوَ السَّمِيعُ الْعَلِيمُ
And if they incline to peace, then incline to it [also] and rely upon Allah. Indeed, it is He who is the Hearing, the Knowing. (8:61)


So, we cannot compare Jihad to the terrorist or the acts of the terrorist groups in the name Islam now.

Worldly Life and Hereafter



Asceticism
The atheists believe that there is no life after death. On the contrary, all Abrahamic religions believe in doomsday which is the end of the worldly life, and judgment day when the dead will be resurrected from their graves to hold accountable for their deeds in the worldly life. Because they believe in God, and He is fair and just, so He will not let the bad people be equal to the good people, they believe the humans have two different lives: the first one is the worldly life on the earth, and the other one is the hereafter in the heavens or the hell fire, based on their deeds in the first life in all Abrahamic religions.
That is why some followers of Abrahamic religions think that we need to avoid the pleasures of this worldly life in order to be closer to God and get the pleasures of paradise in the hereafter. That is why calls for asceticism were spread.
This idea could fit the Christianity, especially in some Catholic and Orthodox dimensions, where the monks and nuns renounce worldly pursuits to devote oneself fully to spiritual work, and live in monasteries to stay away from the secular world; because Jesus said in the John’s gospel:
"My kingdom is not of this world. If it were, my servants would fight to prevent my arrest by the Jewish leaders.” John 18:33-38

So, he separated the worldly life from the heavenly life. Also, he said in the Matthew’s gospel:
 “Give back to Caesar what is Caesar’s, and to God what is God’s.” Matthew 22:22

The Christian European societies accepted secularism as a solution to the Church's control over the state; because the idea of secularism (the separation between the state and the church) fits the Christianity that separates the worldly life from the hereafter.
Some Islamic schools, such as sufism and asceticism, developed this idea to divide people into three levels. The first level is atheists who deny the hereafter. The second level is the regular believers who seek both lives. The third level is the best believers who seek the hereafter only, and do not care about the worldly life.


In the modern era, this idea became very dangerous, because the terrorists groups used it to recruit and mobilization the young Muslims to serve their goals and plans. In the beginning, they isolate themselves from their families and societies, and then turn aganist them.

Islam values the worldly life
This idea is strange in Islam. Yes, the belief in the judgment day is one of the six pillars of the faith in Islam, but there is no Monasticism or monkhood in Islam. Islam values the worldly life and its future until the end of last minute, as the prophet Muhammad said:
إِنْ قَامَتِ السَّاعَةُ وَفِي يَدِ أَحَدِكُمْ فَسِيلَةٌ، فَإِنِ اسْتَطَاعَ أَنْ لاَ تَقُومَ حَتَّى يَغْرِسَهَا فَلْيَغْرِسْهَا‏.‏
“If the Day of Judgment comes while you are planting a new tree, carry on and plant it”
Source: Musnad Ahmad 12491 - Grade: Sahih (authentic) according to Al-Haythami – (Authinticated by Al-Albani):

Protecting the life is one of the five objectives of the Islamic law (Shari’ah), and Quran considers saving one’s life as saving mankind entirely.
مَن قَتَلَ نَفْسًا بِغَيْرِ نَفْسٍ أَوْ فَسَادٍ فِي الْأَرْضِ فَكَأَنَّمَا قَتَلَ النَّاسَ جَمِيعًا وَمَنْ أَحْيَاهَا فَكَأَنَّمَا أَحْيَا النَّاسَ جَمِيعًا ۚ وَلَقَدْ جَاءَتْهُمْ رُسُلُنَا بِالْبَيِّنَاتِ ثُمَّ إِنَّ كَثِيرًا مِّنْهُم بَعْدَ ذَٰلِكَ فِي الْأَرْضِ لَمُسْرِفُونَ
whoever kills a soul unless for a soul or for corruption [done] in the land - it is as if he had slain mankind entirely. And whoever saves one - it is as if he had saved mankind entirely. (5:32)

Enjoying the worldly life is not a sin
After Adam and Eve ate from the forbidden tree, God introduced the worldly life on the earth to them as an enjoyment.
فَأَزَلَّهُمَا الشَّيْطَانُ عَنْهَا فَأَخْرَجَهُمَا مِمَّا كَانَا فِيهِ ۖ وَقُلْنَا اهْبِطُوا بَعْضُكُمْ لِبَعْضٍ عَدُوٌّ ۖ وَلَكُمْ فِي الْأَرْضِ مُسْتَقَرٌّ وَمَتَاعٌ إِلَىٰ حِينٍ
But Satan caused them to slip out of it and removed them from that [condition] in which they had been. And We said, "Go down, [all of you], as enemies to one another, and you will have upon the earth a place of settlement and an enjoyment for a time." (2:36)

So enjoying the worldly life is not a sin. It does not make you away of God. Actually, it is the tradition of prophet Muhammad, and whoever does not follow his tradition is not from his followers.
حَدَّثَنَا سَعِيدُ بْنُ أَبِي مَرْيَمَ، أَخْبَرَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، أَخْبَرَنَا حُمَيْدُ بْنُ أَبِي حُمَيْدٍ الطَّوِيلُ، أَنَّهُ سَمِعَ أَنَسَ بْنَ مَالِكٍ ـ رضى الله عنه ـ يَقُولُ جَاءَ ثَلاَثَةُ رَهْطٍ إِلَى بُيُوتِ أَزْوَاجِ النَّبِيِّ صلى الله عليه وسلم يَسْأَلُونَ عَنْ عِبَادَةِ النَّبِيِّ صلى الله عليه وسلم فَلَمَّا أُخْبِرُوا كَأَنَّهُمْ تَقَالُّوهَا فَقَالُوا وَأَيْنَ نَحْنُ مِنَ النَّبِيِّ صلى الله عليه وسلم قَدْ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ وَمَا تَأَخَّرَ‏.‏ قَالَ أَحَدُهُمْ أَمَّا أَنَا فَإِنِّي أُصَلِّي اللَّيْلَ أَبَدًا‏.‏ وَقَالَ آخَرُ أَنَا أَصُومُ الدَّهْرَ وَلاَ أُفْطِرُ‏.‏ وَقَالَ آخَرُ أَنَا أَعْتَزِلُ النِّسَاءَ فَلاَ أَتَزَوَّجُ أَبَدًا‏.‏ فَجَاءَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ ‏ "‏ أَنْتُمُ الَّذِينَ قُلْتُمْ كَذَا وَكَذَا أَمَا وَاللَّهِ إِنِّي لأَخْشَاكُمْ لِلَّهِ وَأَتْقَاكُمْ لَهُ، لَكِنِّي أَصُومُ وَأُفْطِرُ، وَأُصَلِّي وَأَرْقُدُ وَأَتَزَوَّجُ النِّسَاءَ، فَمَنْ رَغِبَ عَنْ سُنَّتِي فَلَيْسَ مِنِّي ‏"‏‏.‏
Narrated Anas bin Malik: A group of three men came to the houses of the wives of the Prophet asking how the Prophet worshipped (Allah), and when they were informed about that, they considered their worship insufficient and said, "Where are we from the Prophet as his past and future sins have been forgiven." Then one of them said, "I will offer the prayer throughout the night forever." The other said, "I will fast throughout the year and will not break my fast." The third said, "I will keep away from the women and will not marry forever." Allah's Messenger came to them and said, "Are you the same people who said so-and-so? By Allah, I am more submissive to Allah and more afraid of Him than you; yet I fast and break my fast, I do sleep and I also marry women. So he who does not follow my tradition in religion, is not from me (not one of my followers).

God has forbidden us to forget enjoying the worldly life.
وَلَا تَنسَ نَصِيبَكَ مِنَ الدُّنْيَا
and [yet], do not forget your share of the world. (28:77)

He has produced for us the adornment and the good [lawful] things of provision, He encourages us to enjoy them, and He has forbidden us to disallow others enjoying these adornment and the good things of provision.
يَا بَنِي آدَمَ خُذُوا زِينَتَكُمْ عِندَ كُلِّ مَسْجِدٍ وَكُلُوا وَاشْرَبُوا وَلَا تُسْرِفُوا ۚ إِنَّهُ لَا يُحِبُّ الْمُسْرِفِينَ . قُلْ مَنْ حَرَّمَ زِينَةَ اللَّهِ الَّتِي أَخْرَجَ لِعِبَادِهِ وَالطَّيِّبَاتِ مِنَ الرِّزْقِ ۚ قُلْ هِيَ لِلَّذِينَ آمَنُوا فِي الْحَيَاةِ الدُّنْيَا خَالِصَةً يَوْمَ الْقِيَامَةِ ۗ كَذَٰلِكَ نُفَصِّلُ الْآيَاتِ لِقَوْمٍ يَعْلَمُونَ . قُلْ إِنَّمَا حَرَّمَ رَبِّيَ الْفَوَاحِشَ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ وَالْإِثْمَ وَالْبَغْيَ بِغَيْرِ الْحَقِّ وَأَن تُشْرِكُوا بِاللَّهِ مَا لَمْ يُنَزِّلْ بِهِ سُلْطَانًا وَأَن تَقُولُوا عَلَى اللَّهِ مَا لَا تَعْلَمُونَ
O children of Adam, take your adornment at every mosque, and eat and drink, but be not excessive. Indeed, He likes not those who commit excess.
Say, "Who has forbidden the adornment of Allah which He has produced for His servants and the good [lawful] things of provision?" Say, "They are for those who believe during the worldly life [but] exclusively for them on the Day of Resurrection." Thus do We detail the verses for a people who know.
Say, "My Lord has only forbidden immoralities - what is apparent of them and what is concealed - and sin, and oppression without right, and that you associate with Allah that for which He has not sent down authority, and that you say about Allah that which you do not know." (7:31-33)

Conditions of enjoying the worldly life
As we see in last verse, the Quran encourages Muslims to enjoy the pleasures of their worldly life, but it warns them of squandering or prodigality. So there is a limit of enjoying the pleasures of their worldly life. This limit is forgetting the hereafter.
فَمَا أُوتِيتُم مِّن شَيْءٍ فَمَتَاعُ الْحَيَاةِ الدُّنْيَا ۖ وَمَا عِندَ اللَّهِ خَيْرٌ وَأَبْقَىٰ لِلَّذِينَ آمَنُوا وَعَلَىٰ رَبِّهِمْ يَتَوَكَّلُونَ
So whatever thing you have been given - it is but [for] enjoyment of the worldly life. But what is with Allah is better and more lasting for those who have believed and upon their Lord rely. (42:36)

So the problem is not enjoying the worldly life, but preferring it over the hereafter, or focusing on it and ignoring the hereafter.
بَلْ تُؤْثِرُونَ الْحَيَاةَ الدُّنْيَا . وَالْآخِرَةُ خَيْرٌ وَأَبْقَىٰ
But you prefer the worldly life, While the Hereafter is better and more enduring. (87:16-17(

That is exactly what the atheists do. That is why God advised his prophet Muhammad not to waste his time with atheists, whether he warned them or did not, they would not accept his message, because they already deny the hereafter.
فَأَعْرِضْ عَن مَّن تَوَلَّىٰ عَن ذِكْرِنَا وَلَمْ يُرِدْ إِلَّا الْحَيَاةَ الدُّنْيَا
So turn away from whoever turns his back on Our message and desires nothing but the life of this world. (53:29)

The prophet Muhammad said:
"كُنْ فِي الدُّنْيَا كَأَنَّك غَرِيبٌ أَوْ عَابِرُ سَبِيلٍ
 On the authority of Abdullah ibn Umar (May Allah be pleased with them both), he relates that the Prophet (Peace be upon him) once held my shoulders and said: “Live in this world as (if you are) a stranger or a wayfarer.” [Sahîh al-Bukhârî (7/170)]

This does not mean do not enjoy the worldly life , but do not be so attached to it. If you are so attached to the worldly life you will try to enjoy it even in a sinful way.  If you are so attached to your kids you would commit a suicide if they die. If you are so attached to your wife you will have no problem to sin to please her. If you are so attached to your parent you would obey them even if they endeavor to make you associate with God another deity.
وَوَصَّيْنَا الْإِنسَانَ بِوَالِدَيْهِ حَمَلَتْهُ أُمُّهُ وَهْنًا عَلَىٰ وَهْنٍ وَفِصَالُهُ فِي عَامَيْنِ أَنِ اشْكُرْ لِي وَلِوَالِدَيْكَ إِلَيَّ الْمَصِيرُ . وَإِن جَاهَدَاكَ عَلَىٰ أَن تُشْرِكَ بِي مَا لَيْسَ لَكَ بِهِ عِلْمٌ فَلَا تُطِعْهُمَا ۖ وَصَاحِبْهُمَا فِي الدُّنْيَا مَعْرُوفًا
And We have enjoined upon man [care] for his parents. His mother carried him, [increasing her] in weakness upon weakness, and his weaning is in two years. Be grateful to Me and to your parents; to Me is the [final] destination. But if they endeavor to make you associate with Me that of which you have no knowledge, do not obey them but accompany them in [this] world with appropriate kindness. (31:14-15)

If you are so attached to the worldly life, even without any quality or right, you would accept the oppression, and you would not try to defend yourself, or fight for your rights.
إِنَّ اللَّهَ اشْتَرَىٰ مِنَ الْمُؤْمِنِينَ أَنفُسَهُمْ وَأَمْوَالَهُم بِأَنَّ لَهُمُ الْجَنَّةَ ۚ يُقَاتِلُونَ فِي سَبِيلِ اللَّهِ  
Indeed, Allah has purchased from the believers their lives and their properties [in exchange] for that they will have Paradise. They fight in the cause of Allah. (9:111)

It is a sin when you wrong yourself and accept this type of life like animals, so if you have weakness and you cannot fight for your life, Quran encourages you to move to another land where you can have a better life as the human that God honor.
إِنَّ الَّذِينَ تَوَفَّاهُمُ الْمَلَائِكَةُ ظَالِمِي أَنفُسِهِمْ قَالُوا فِيمَ كُنتُمْ ۖ قَالُوا كُنَّا مُسْتَضْعَفِينَ فِي الْأَرْضِ ۚ قَالُوا أَلَمْ تَكُنْ أَرْضُ اللَّهِ وَاسِعَةً فَتُهَاجِرُوا فِيهَا ۚ فَأُولَٰئِكَ مَأْوَاهُمْ جَهَنَّمُ ۖ وَسَاءَتْ مَصِيرًا
Indeed, those whom the angels take [in death] while wronging themselves - [the angels] will say, "In what [condition] were you?" They will say, "We were oppressed in the land." The angels will say, "Was not the earth of Allah spacious [enough] for you to emigrate therein?" For those, their refuge is Hell - and evil it is as a destination. (4:79)

The pleasures of this worldly life, such as wealth, children and wives, are a trial. If you are so attached to them they would be your enemies. It is like a lot of inmates when they say that they had sold drugs to support their families.
يَا أَيُّهَا الَّذِينَ آمَنُوا إِنَّ مِنْ أَزْوَاجِكُمْ وَأَوْلَادِكُمْ عَدُوًّا لَّكُمْ فَاحْذَرُوهُمْ ۚ وَإِن تَعْفُوا وَتَصْفَحُوا وَتَغْفِرُوا فَإِنَّ اللَّهَ غَفُورٌ رَّحِيمٌ . إِنَّمَا أَمْوَالُكُمْ وَأَوْلَادُكُمْ فِتْنَةٌ ۚ وَاللَّهُ عِندَهُ أَجْرٌ عَظِيمٌ . فَاتَّقُوا اللَّهَ مَا اسْتَطَعْتُمْ وَاسْمَعُوا وَأَطِيعُوا وَأَنفِقُوا خَيْرًا لِّأَنفُسِكُمْ ۗ وَمَن يُوقَ شُحَّ نَفْسِهِ فَأُولَٰئِكَ هُمُ الْمُفْلِحُونَ
O you who have believed, indeed, among your wives and your children are enemies to you, so beware of them. But if you pardon and overlook and forgive - then indeed, Allah is Forgiving and Merciful.
Your wealth and your children are but a trial, and Allah has with Him a great reward.
So fear Allah as much as you are able and listen and obey and spend [in the way of Allah ]; it is better for your selves. And whoever is protected from the stinginess of his soul - it is those who will be the successful. (64:14-16)

The Quran remind us that the enjoyment of the worldly life is for a time (while) but not forever, like the hereafter. 
وَمَا هَٰذِهِ الْحَيَاةُ الدُّنْيَا إِلَّا لَهْوٌ وَلَعِبٌ ۚ وَإِنَّ الدَّارَ الْآخِرَةَ لَهِيَ الْحَيَوَانُ ۚ لَوْ كَانُوا يَعْلَمُونَ
And this worldly life is not but diversion and amusement. And indeed, the home of the Hereafter - that is the [eternal] life, if only they knew. (29:64)

The hereafter is the eternity, so if we have to prefer one life over the other we should prefer the hereafter, but God does not ask us to do it.
يَا قَوْمِ إِنَّمَا هَٰذِهِ الْحَيَاةُ الدُّنْيَا مَتَاعٌ وَإِنَّ الْآخِرَةَ هِيَ دَارُ الْقَرَارِ
O my people, this worldly life is only [temporary] enjoyment, and indeed, the Hereafter - that is the home of [permanent] settlement. (40:39)

Quran warned us of being deluded or deceived by the enjoyments of the worldly life. Yes, enjoy the life but do not let it delude or deceive you.
يَا أَيُّهَا النَّاسُ اتَّقُوا رَبَّكُمْ وَاخْشَوْا يَوْمًا لَّا يَجْزِي وَالِدٌ عَن وَلَدِهِ وَلَا مَوْلُودٌ هُوَ جَازٍ عَن وَالِدِهِ شَيْئًا ۚ إِنَّ وَعْدَ اللَّهِ حَقٌّ ۖ فَلَا تَغُرَّنَّكُمُ الْحَيَاةُ الدُّنْيَا وَلَا يَغُرَّنَّكُم بِاللَّهِ الْغَرُورُ
O mankind, fear your Lord and fear a Day when no father will avail his son, nor will a son avail his father at all. Indeed, the promise of Allah is truth, so let not the worldly life delude you and be not deceived about Allah by the Deceiver. (31:33)

Also, the Quran warned us of the punishment of those who work very hard to gain the worldly life and ignore the hereafter.
الَّذِينَ يَسْتَحِبُّونَ الْحَيَاةَ الدُّنْيَا عَلَى الْآخِرَةِ وَيَصُدُّونَ عَن سَبِيلِ اللَّهِ وَيَبْغُونَهَا عِوَجًا ۚ أُولَٰئِكَ فِي ضَلَالٍ بَعِيدٍ
The ones who prefer the worldly life over the Hereafter and avert [people] from the way of Allah , seeking to make it (seem) deviant. Those are in extreme error. (14:3)

The Quran describes these people as those who buy this worldly life in exchange for the hereafter.
أُولَٰئِكَ الَّذِينَ اشْتَرَوُا الْحَيَاةَ الدُّنْيَا بِالْآخِرَةِ ۖ فَلَا يُخَفَّفُ عَنْهُمُ الْعَذَابُ وَلَا هُمْ يُنصَرُونَ
Those are the ones who have bought the life of this world [in exchange] for the Hereafter, so the punishment will not be lightened for them, nor will they be aided. (2:86)

On the contrary, the Quran do not ask Muslims to buy the hereafter in exchange for the worldly life. Rather Islam wants the humans to enjoy both lives.
مَن كَانَ يُرِيدُ حَرْثَ الْآخِرَةِ نَزِدْ لَهُ فِي حَرْثِهِ ۖ وَمَن كَانَ يُرِيدُ حَرْثَ الدُّنْيَا نُؤْتِهِ مِنْهَا وَمَا لَهُ فِي الْآخِرَةِ مِن نَّصِيبٍ
Whoever desires the harvest of the Hereafter - We increase for him in his harvest. And whoever desires the harvest of this world - We give him thereof, but there is not for him in the Hereafter any share. (42:20)

The Quran describes the believers as the people who seek for the good in both lives: the worldly life and the hereafter, not only the hereafter.
فَإِذَا قَضَيْتُم مَّنَاسِكَكُمْ فَاذْكُرُوا اللَّهَ كَذِكْرِكُمْ آبَاءَكُمْ أَوْ أَشَدَّ ذِكْرًا ۗ فَمِنَ النَّاسِ مَن يَقُولُ رَبَّنَا آتِنَا فِي الدُّنْيَا وَمَا لَهُ فِي الْآخِرَةِ مِنْ خَلَاقٍ . وَمِنْهُم مَّن يَقُولُ رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الْآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ . أُولَٰئِكَ لَهُمْ نَصِيبٌ مِّمَّا كَسَبُوا ۚ وَاللَّهُ سَرِيعُ الْحِسَابِ
And when you have completed your rites, remember Allah like your [previous] remembrance of your fathers or with [much] greater remembrance. And among the people is he who says, "Our Lord, give us in this world," and he will have in the Hereafter no share.
But among them is he who says, "Our Lord, give us in this world [that which is] good and in the Hereafter [that which is] good and protect us from the punishment of the Fire."
Those will have a share of what they have earned, and Allah is swift in account. (2: 200-202)

Balance in life
Islam does not separate the worldly life from the hereafter.
قُلْ إِنَّ صَلَاتِي وَنُسُكِي وَمَحْيَايَ وَمَمَاتِي لِلَّهِ رَبِّ الْعَالَمِينَ
Say, "Indeed, my prayer, my rites of sacrifice, my living and my dying are for The God, Lord of the worlds. 6:162

Actually, Islam challenges us to keep attaining balance in life, as the prophet said:
اعمل لدنياك كأنك تعيش أبداً واعمل لآخرتك كأنك تموت غدا
“Work for this life as though you are going to live forever, and work for the hereafter as though you will die tomorrow.”

But how can we do that? If I know that I will live forever I will go to try to get more educational degrees, work more, save much money as I can, buy nice house and car, and have more kids. But if I know that I will die tomorrow I will donate all my wealth and everything I own as charity and spend all my time in prayer and worship. The Quran gives us a good instruction to gain both lives.
وَابْتَغِ فِيمَا آتَاكَ اللَّهُ الدَّارَ الْآخِرَةَ ۖ وَلَا تَنسَ نَصِيبَكَ مِنَ الدُّنْيَا ۖ وَأَحْسِن كَمَا أَحْسَنَ اللَّهُ إِلَيْكَ ۖ وَلَا تَبْغِ الْفَسَادَ فِي الْأَرْضِ ۖ إِنَّ اللَّهَ لَا يُحِبُّ الْمُفْسِدِينَ
But seek, through that which Allah has given you, the home of the Hereafter; and [yet], do not forget your share of the world. And do good as Allah has done good to you. And desire not corruption in the land. Indeed, Allah does not like corrupters." (28:77)

This instruction is to do your worldly deeds, intend them for God, and avoid the sin. Prophet Muhammad said:
"‏ إِنَّمَا الأَعْمَالُ بِالنِّيَّاتِ وَإِنَّمَا لِكُلِّ امْرِئٍ مَا نَوَى فَمَنْ كَانَتْ هِجْرَتُهُ إِلَى اللَّهِ وَرَسُولِهِ فَهِجْرَتُهُ إِلَى اللَّهِ وَرَسُولِهِ وَمَنْ كَانَتْ هِجْرَتُهُ لِدُنْيَا يُصِيبُهَا أَوِ امْرَأَةٍ يَتَزَوَّجُهَا فَهِجْرَتُهُ إِلَى مَا هَاجَرَ إِلَيْهِ ‏"‏ ‏.‏
“All actions are judged by motives, and each person will be rewarded according to their intention.“ Bukhari :: Book 1 :: Volume 1 :: Hadith 1

That means the worship in Islam is not just limited to the rituals. The worship includes all your deeds, even worldly daily deeds, such as eating, drinking or having sex, if you intend it for God. It is worship when you choose to eat beef or lamb to avoid pork. It is worship when you choose to drink water, juice or milk to avoid alcohol. It is worship when you choose to have sex with your wife to avoid fornication. It is worship when you choose to avoid the sin.
وَالَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ أُولَٰئِكَ أَصْحَابُ الْجَنَّةِ ۖ هُمْ فِيهَا خَالِدُونَ
But they who believe and do righteous deeds - those are the companions of Paradise; they will abide therein eternally. (2:82)

Why is the paradise only for those who believe and have good deeds? Belief only is not good enough, and good deeds only is not good enough.
First, logically you cannot be something you deny. You will not go to a school if you deny there is a school. Same thing you cannot go to the paradise if you deny it.

Second, the paradise in hereafter will be for those who try to make the worldly life as a paradise on the earth, by improving it and helping others. That is the good deeds.
