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 if grace from Allah come to you, he would certainly cry out, as if there had not been any friendship between you and him: Would that I had been with them, then I should have attained a mighty good fortune. 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 what is [the matter] with you that you fight not in the cause of Allah and [for] the oppressed among men, women, and children who say, "Our Lord, take us out of this city of oppressive people and appoint for us from Yourself a protector and appoint for us from Yourself a helper?" 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
