Believers, if you yield to those who deny the truth, they will cause you to turn back on your heels and you will turn into losers. 149 No, indeed! it is God who is your protector: He is the best supporter. 150 We shall cast terror into the hearts of those who disbelieve because they ascribe unto Allah partners, for which no warrant hath been revealed. Their habitation is the Fire, and hapless the abode of the wrong-doers. 151 And indeed Allah has proved true His promise to you, when you used to slay the disbelievers by His command; until the time you people lost courage and disputed about the order and disobeyed after Allah had shown you what pleases you; some of you desired the world, and some of you desired the Hereafter; thereafter He turned you away from them in order to test you; and undoubtedly He has forgiven you; and Allah is Most Munificent towards the Muslims. 152 ۞ When you ran off precipitately and did not wait for any one, and the Apostle was calling you from your rear, so He gave you another sorrow instead of (your) sorrow, so that you might not grieve at what had escaped you, nor (at) what befell you; and Allah is aware of what you do. 153 Then after distress, He sent down upon you security [in the form of] drowsiness, overcoming a faction of you, while another faction worried about themselves, thinking of Allah other than the truth - the thought of ignorance, saying, "Is there anything for us [to have done] in this matter?" Say, "Indeed, the matter belongs completely to Allah." They conceal within themselves what they will not reveal to you. They say, "If there was anything we could have done in the matter, some of us would not have been killed right here." Say, "Even if you had been inside your houses, those decreed to be killed would have come out to their death beds." [It was] so that Allah might test what is in your breasts and purify what is in your hearts. And Allah is Knowing of that within the breasts. 154 Indeed, those of you who turned back on the day the two armies met, it was Satan who caused them to slip because of some [blame] they had earned. But Allah has already forgiven them. Indeed, Allah is Forgiving and Forbearing. 155
