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 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 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).
