Believers! Always be on your guard against encounters. Then (as circumstance demands) either advance in detachments or advance in a body. 71 Someone among you will surely lag behind, and if calamity should befall you, will say: "God was gracious to me that I was not among them." 72 And were you to receive Allah’s munificence (a bounty), he would surely say – as if there had been no friendship between you and him – “Alas – if only I had been with them, I would have achieved a great success!” 73 ۞ Let those fight in the way of Allah who sell the life of this world for the other. Whoso fighteth in the way of Allah, be he slain or be he victorious, on him We shall bestow a vast reward. 74 And how should you not fight for the cause of God, and for the helpless old men, women, and children who say, "Deliver us, Lord, from this city of wrongdoers, grant us a protector out of Your grace and grant us a supporter out of Your grace?" 75 These who believe fight in the way of Allah and those who disbelieve fight in the way of the devil. Fight then against the friends of Satan; verily the craft of Satan is ever feeble. 76
