Al-Baqarah 2:246

أَلَمۡ تَرَ إِلَى ٱلۡمَلَإِ مِنۢ بَنِيٓ إِسۡرَـٰٓءِيلَ 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 بِٱلظَّـٰلِمِينَ 246

Have you not considered the assembly of the Children of Israel after [the time of] Moses when they said to a prophet of theirs, "Send to us a king, and we will fight in the way of Allah "? He said, "Would you perhaps refrain from fighting if fighting was prescribed for you?" They said, "And why should we not fight in the cause of Allah when we have been driven out from our homes and from our children?" But when fighting was prescribed for them, they turned away, except for a few of them. And Allah is Knowing of the wrongdoers
