So, when you meet those who disbelieve in war, smite at their necks (without giving them opportunity to defeat you). At length, when you have sufficiently suppressed them, (without continuing fighting) bind a firm bond of captivity on them. Then set them free either as a favor without demanding anything in return, or for ransom (which may consist of a reciprocal exchange of prisoners of war), so that warfare may abandon weapons and come to an end. That (is God’s command). Had God so willed, He would certainly exact retribution from them (Himself), but (He orders you to fight) in order to try you by means of one another. As for those who are killed in God’s cause, He will never render their deeds vain.
