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 And if a bounty from Allah befell you, he would surely cry, as if there had been no love between you and him: Oh, would that I had been with them, then should I have achieved a great success! 73 ۞ Therefore let those fight in the way of Allah, who sell this world's life for the hereafter; and whoever fights in the way of Allah, then be he slain or be he victorious, We shall grant him a mighty 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 The believers fight in the way of God, and the unbelievers fight in the idols' way. Fight you therefore against the friends of Satan; surely the guile of Satan is ever feeble. 76
