Believers! Always be on your guard against encounters. Then (as circumstance demands) either advance in detachments or advance in a body. 71 And verily there is among you he who laggeth behind, and if an ill befalleth you, he saith: surely Allah hath bestowed favour on me in that I was not present with them. 72 But if a bounty from God visits you, he will surely say, as if there had never been any affection between you and him, 'Would that I had been with them, to attain a mighty triumph!' 73 ۞ Those who barter the life of this world for the next should fight in the way of God. And We shall bestow on him who fights in the way of God, whether he is killed or is victorious, a glorious 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 Those who believe fight in the cause of Allah, and those who reject Faith Fight in the cause of Evil: So fight ye against the friends of Satan: feeble indeed is the cunning of Satan. 76
