Believers, take your precautions. March in detachments or march all together. 71 And behold, there are indeed among you such as would lag behind, and then, if calamity befalls you, say: "God has bestowed His favour upon me in that I did not accompany them." 72 But if, by God's grace, good fortune should be your lot, they will say, "If only I had been with them I should have achieved a great success," as if no affection had existed between you and them. 73 ۞ So those who sell the life of this world for the Hereafter, must fight in Allah's cause; and We shall bestow a great reward upon whoever fights in Allah's cause, whether he is martyred or is victorious. 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 do battle for the cause of Allah; and those who disbelieve do battle for the cause of idols. So fight the minions of the devil. Lo! the devil's strategy is ever weak. 76
