Believers! Always be on your guard against encounters. Then (as circumstance demands) either advance in detachments or advance in a body. 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 ۞ Let those fight in the way of Allah who sell the life of this world for the other. Whoso fighteth in the way of Allah, be he slain or be he victorious, on him We shall bestow a vast reward. 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 Those who believe fight in the cause of Allah, and those who disbelieve fight in the cause of Taghut. So fight against the allies of Satan. Indeed, the plot of Satan has ever been weak. 76
