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 a bounty from God visits you, he will surely say, as if there had never been any affection between you and him, 'Would that I had been with them, to attain a mighty triumph!' 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 what reason have you that you should not fight in the way of Allah and of the weak among the men and the women and the children, (of) those who say: Our Lord! cause us to go forth from this town, whose people are oppressors, and give us from Thee a guardian and give 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
