O believers, if you listen to the infidels they will make you turn your backs, and you will be the losers. 149 Nay, but God alone is your Lord Supreme, and His is the best succour. 150 We will throw terror into the hearts of those who disbelieve. For that they have associated with Allah that which He did not send down for a proof. Fire shall be their home, evil indeed is the dwellingplace of the harmdoers. 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 ۞ And recall what time ye were running off and would not look back on any one, albeit the apostle in your rear was calling unto you. Wherefore He caused sorrow to overtake you for sorrow, that ye might not grieve for that which ye might lose nor for that which might befall you. And Allah is Aware of that which ye work. 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
