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 And if a bounty from Allah is given you, he says - and says as if there never was any affection between you and him - 'Oh, would that I had been with them, I would have come by a great gain. 73 ۞ Those who want to buy the life hereafter with this life should fight for the cause of God. We will give them a great reward whether they are killed or whether they are victorious. 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 And those who believe fight in the way of Allah, but those who disbelieve fight in the way of the idol. Therefore, fight against those guided by satan. Indeed, satan's guile is always weak. 76
