Believers! Always be on your guard against encounters. Then (as circumstance demands) either advance in detachments or advance in a body. 71 And indeed, there is among you he who lingers behind; and if disaster strikes you, he says, "Allah has favored me in that I was not present with them." 72 And if there betideth you grace from Allah, then, as though there had been no tenderness between you and him, he saith: would that I had been with them! then I would have achieved a mighty achievement. 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 Those who have attained to faith fight in the cause of God, whereas those who are bent on denying the truth fight in the cause of the powers of evil. Fight, then, against those friends of Satan: verily, Satan's guile is weak indeed! 76
