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 good fortune comes to you from God, such a person is sure to say - just as if there had never been any question of love between you and him: "Oh, would that I had been with them, and thus had a [share in their] mighty triumph!" 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 How is it with you, that you do not fight in the way of God, and for the men, women, and children who, being abased, say, 'Our Lord, bring us forth from this city whose people are evildoers, and appoint t us a protector from Thee, and appoint to us from Thee a helper'? 75 The believers fight for the cause of God, while those who reject faith fight for Satan. Then fight the allies of Satan: Satan's scheming is truly weak. 76
