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 God is your Guardian and the best Helper. 150 We will cast terror into the hearts of those who have denied the Truth since they have associated others with Allah in His divinity - something for which He has sent down no sanction. The Fire is their abode; how bad the resting place of the wrong-doers will be! 151 Allah verily made good His promise unto you when ye routed them by His leave, until (the moment) when your courage failed you, and ye disagreed about the order and ye disobeyed, after He had shown you that for which ye long. Some of you desired the world, and some of you desired the Hereafter. Therefore He made you flee from them, that He might try you. Yet now He hath forgiven you. Allah is a Lord of Kindness to believers. 152 ۞ [Remember] when you [fled and] climbed [the mountain] without looking aside at anyone while the Messenger was calling you from behind. So Allah repaid you with distress upon distress so you would not grieve for that which had escaped you [of victory and spoils of war] or [for] that which had befallen you [of injury and death]. And Allah is [fully] Acquainted with 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
