Chapter 2, Verse 217, The Cow
سُوۡرَةُ البَقَرَة
يَسۡـَٔلُونَكَ عَنِ ٱلشَّهۡرِ ٱلۡحَرَامِ قِتَالٖ فِيهِۖ قُلۡ قِتَالٞ فِيهِ كَبِيرٞۚ وَصَدٌّ عَن سَبِيلِ ٱللَّهِ وَكُفۡرُۢ بِهِۦ وَٱلۡمَسۡجِدِ ٱلۡحَرَامِ وَإِخۡرَاجُ أَهۡلِهِۦ مِنۡهُ أَكۡبَرُ عِندَ ٱللَّهِۚ وَٱلۡفِتۡنَةُ أَكۡبَرُ مِنَ ٱلۡقَتۡلِۗ وَلَا يَزَالُونَ يُقَٰتِلُونَكُمۡ حَتَّىٰ يَرُدُّوكُمۡ عَن دِينِكُمۡ إِنِ ٱسۡتَطَٰعُواْۚ وَمَن يَرۡتَدِدۡ مِنكُمۡ عَن دِينِهِۦ فَيَمُتۡ وَهُوَ كَافِرٞ فَأُوْلَٰٓئِكَ حَبِطَتۡ أَعۡمَٰلُهُمۡ فِي ٱلدُّنۡيَا وَٱلۡأٓخِرَةِۖ وَأُوْلَٰٓئِكَ أَصۡحَٰبُ ٱلنَّارِۖ هُمۡ فِيهَا خَٰلِدُونَ
They ask you concerning fighting in the Sacred Months (i.e. 1st, 7th, 11th and 12th months of the Islamic calendar). Say, "fighting therein is a great (transgression) but a greater (transgression) with Allah is to prevent mankind from following the Way of Allah, to disbelieve in Him, to prevent access to Al-Masjid-al-Haram (at Makkah), and to drive out its inhabitants, and Al-Fitnah is worse than killing. And they will never cease fighting you until they turn you back from your religion (Islamic Monotheism) if they can. And whosoever of you turns back from his religion and dies as a disbeliever, then his deeds will be lost in this life and in the Hereafter, and they will be the dwellers of the Fire. They will abide therein forever.
Chapter 2, Verse 246, The Cow
سُوۡرَةُ البَقَرَة
أَلَمۡ تَرَ إِلَى ٱلۡمَلَإِ مِنۢ بَنِيٓ إِسۡرَٰٓءِيلَ مِنۢ بَعۡدِ مُوسَىٰٓ إِذۡ قَالُواْ لِنَبِيّٖ لَّهُمُ ٱبۡعَثۡ لَنَا مَلِكٗا نُّقَٰتِلۡ فِي سَبِيلِ ٱللَّهِۖ قَالَ هَلۡ عَسَيۡتُمۡ إِن كُتِبَ عَلَيۡكُمُ ٱلۡقِتَالُ أَلَّا تُقَٰتِلُواْۖ قَالُواْ وَمَا لَنَآ أَلَّا نُقَٰتِلَ فِي سَبِيلِ ٱللَّهِ وَقَدۡ أُخۡرِجۡنَا مِن دِيَٰرِنَا وَأَبۡنَآئِنَاۖ فَلَمَّا كُتِبَ عَلَيۡهِمُ ٱلۡقِتَالُ تَوَلَّوۡاْ إِلَّا قَلِيلٗا مِّنۡهُمۡۚ وَٱللَّهُ عَلِيمُۢ بِٱلظَّٰلِمِينَ
Have you not thought about the group of the Children of Israel after (the time of) Musa (Moses)? When they said to a Prophet of theirs, "Appoint for us a king and we will fight in Allah's Way." He said, "Would you then refrain from fighting, if fighting was prescribed for you?" They said, "Why should we not fight in Allah's Way while we have been driven out of our homes and our children (families have been taken as captives)?" But when fighting was ordered for them, they turned away, all except a few of them. And Allah is All-Aware of the Zalimun (polytheists and wrong-doers).
Chapter 21, Verse 80, The Prophets
سورة الأنبياء
وَعَلَّمۡنَٰهُ صَنۡعَةَ لَبُوسٖ لَّكُمۡ لِتُحۡصِنَكُم مِّنۢ بَأۡسِكُمۡۖ فَهَلۡ أَنتُمۡ شَٰكِرُونَ
And We taught him the making of metal coats of mail (for battles), to protect you in your fighting. Are you then grateful?
Chapter 22, Verse 39, The Pilgrimage
سورة الحج
أُذِنَ لِلَّذِينَ يُقَٰتَلُونَ بِأَنَّهُمۡ ظُلِمُواْۚ وَإِنَّ ٱللَّهَ عَلَىٰ نَصۡرِهِمۡ لَقَدِيرٌ
Permission to fight is given to those (i.e. believers against disbelievers), who are fighting them, (and) because they (believers) have been wronged, and surely, Allah is Able to give them (believers) victory
Chapter 33, Verse 18, The Coalition
سورة الأحزاب
۞قَدۡ يَعۡلَمُ ٱللَّهُ ٱلۡمُعَوِّقِينَ مِنكُمۡ وَٱلۡقَآئِلِينَ لِإِخۡوَٰنِهِمۡ هَلُمَّ إِلَيۡنَاۖ وَلَا يَأۡتُونَ ٱلۡبَأۡسَ إِلَّا قَلِيلًا
Allah already knows those among you who keep back (men) from fighting in Allah's Cause, and those who say to their brethren "Come here towards us," while they (themselves) come not to the battle except a little.
Chapter 38, Verse 31, Sad
سورة ص
إِذۡ عُرِضَ عَلَيۡهِ بِٱلۡعَشِيِّ ٱلصَّٰفِنَٰتُ ٱلۡجِيَادُ
When there were displayed before him, in the afternoon, well trained horses of the highest breed [for Jihad (holy fighting in Allah's Cause)].
Chapter 47, Verse 20, Muhammad
سورة محمد
وَيَقُولُ ٱلَّذِينَ ءَامَنُواْ لَوۡلَا نُزِّلَتۡ سُورَةٞۖ فَإِذَآ أُنزِلَتۡ سُورَةٞ مُّحۡكَمَةٞ وَذُكِرَ فِيهَا ٱلۡقِتَالُ رَأَيۡتَ ٱلَّذِينَ فِي قُلُوبِهِم مَّرَضٞ يَنظُرُونَ إِلَيۡكَ نَظَرَ ٱلۡمَغۡشِيِّ عَلَيۡهِ مِنَ ٱلۡمَوۡتِۖ فَأَوۡلَىٰ لَهُمۡ
Those who believe say: "Why is not a Surah (chapter of the Quran) sent down (for us)? But when a decisive Surah (explaining and ordering things) is sent down, and fighting (Jihad - holy fighting in Allah's Cause) is mentioned (i.e. ordained) therein, you will see those in whose hearts is a disease (of hypocrisy) looking at you with a look of one fainting to death. But it was better for them (hypocrites, to listen to Allah and to obey Him).
Chapter 4, Verse 72, The Women
سورة النساء
وَإِنَّ مِنكُمۡ لَمَن لَّيُبَطِّئَنَّ فَإِنۡ أَصَٰبَتۡكُم مُّصِيبَةٞ قَالَ قَدۡ أَنۡعَمَ ٱللَّهُ عَلَيَّ إِذۡ لَمۡ أَكُن مَّعَهُمۡ شَهِيدٗا
There is certainly among you he who would linger behind (from fighting in Allah's Cause). If a misfortune befalls you, he says, "Indeed Allah has favoured me in that I was not present among them."
Chapter 4, Verse 77, The Women
سورة النساء
أَلَمۡ تَرَ إِلَى ٱلَّذِينَ قِيلَ لَهُمۡ كُفُّوٓاْ أَيۡدِيَكُمۡ وَأَقِيمُواْ ٱلصَّلَوٰةَ وَءَاتُواْ ٱلزَّكَوٰةَ فَلَمَّا كُتِبَ عَلَيۡهِمُ ٱلۡقِتَالُ إِذَا فَرِيقٞ مِّنۡهُمۡ يَخۡشَوۡنَ ٱلنَّاسَ كَخَشۡيَةِ ٱللَّهِ أَوۡ أَشَدَّ خَشۡيَةٗۚ وَقَالُواْ رَبَّنَا لِمَ كَتَبۡتَ عَلَيۡنَا ٱلۡقِتَالَ لَوۡلَآ أَخَّرۡتَنَآ إِلَىٰٓ أَجَلٖ قَرِيبٖۗ قُلۡ مَتَٰعُ ٱلدُّنۡيَا قَلِيلٞ وَٱلۡأٓخِرَةُ خَيۡرٞ لِّمَنِ ٱتَّقَىٰ وَلَا تُظۡلَمُونَ فَتِيلًا
Have you not seen those who were told to hold back their hands (from fighting) and perform As-Salat (Iqamat-as-Salat), and give Zakat, but when the fighting was ordained for them, behold! a section of them fear men as they fear Allah or even more. They say: "Our Lord! Why have you ordained for us fighting? Would that you had granted us respite for a short period?" Say: "Short is the enjoyment of this world. The Hereafter is (far) better for him who fears Allah, and you shall not be dealt with unjustly even equal to the Fatila (a scalish thread in the long slit of a date-stone).
Chapter 4, Verse 90, The Women
سورة النساء
إِلَّا ٱلَّذِينَ يَصِلُونَ إِلَىٰ قَوۡمِۭ بَيۡنَكُمۡ وَبَيۡنَهُم مِّيثَٰقٌ أَوۡ جَآءُوكُمۡ حَصِرَتۡ صُدُورُهُمۡ أَن يُقَٰتِلُوكُمۡ أَوۡ يُقَٰتِلُواْ قَوۡمَهُمۡۚ وَلَوۡ شَآءَ ٱللَّهُ لَسَلَّطَهُمۡ عَلَيۡكُمۡ فَلَقَٰتَلُوكُمۡۚ فَإِنِ ٱعۡتَزَلُوكُمۡ فَلَمۡ يُقَٰتِلُوكُمۡ وَأَلۡقَوۡاْ إِلَيۡكُمُ ٱلسَّلَمَ فَمَا جَعَلَ ٱللَّهُ لَكُمۡ عَلَيۡهِمۡ سَبِيلٗا
Except those who join a group, between you and whom there is a treaty (of peace), or those who approach you with their breasts restraining from fighting you as well as fighting their own people. Had Allah willed, indeed He would have given them power over you, and they would have fought you. So if they withdraw from you, and fight not against you, and offer you peace, then Allah has opened no way for you against them.
