Believers! If you follow those who deny the Truth, they will drive you back on your heels, and you will turn about, losers. 149 But Allah is your Protector, and He is the best of helpers. 150 Soon We shall cast awe in the hearts of disbelievers because they have appointed partners to Allah, for which He has not sent any proof; their destination is hell; and what a wretched abode for the unjust! 151 And Allah had assuredly made good His promise unto you when ye were extirpating them by His leave, until when ye flagged and ye disagreed about the command and ye disobeyed after He had shewn you that for which ye longed. Of you some desired the world and of you some desired the Hereafter, wherefore He turned you away from them that he might prove you; and of a surety He hath pardoned you. And Allah is Gracious unto the believers. 152 ۞ [Remember the time] when you fled, paying no heed to anyone, while at your rear the Apostle was calling out to you - wherefore He requited you with woe in return for [the Apostle's] woe, so that you should not grieve [merely] over what had escaped you, nor over what had befallen you: for God is aware of all that 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 when the two armies met – for it was the devil who caused them to waver, because of some of their deeds; and undoubtedly Allah has forgiven them; indeed Allah is Oft Forgiving, Most Forbearing. 155
