Believers, if you obey the unbelievers, they will turn you back to disbelief and you will become lost. 149 Nay, but God alone is your Lord Supreme, and His is the best succour. 150 We will cast terror into the hearts of those who disbelieve, because they set up with Allah that for which He has sent down no authority, and their abode is the fire, and evil is the abode of the unjust. 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 ۞ Behold! ye were climbing up the high ground, without even casting a side glance at any one, and the Messenger in your rear was calling you back. There did Allah give you one distress after another by way of requital, to teach you not to grieve for (the booty) that had escaped you and for (the ill) that had befallen you. For Allah is well aware of all that ye do. 153 Then, after sorrow, He sent down upon you safety. Slumber overtook a party, while another party cared only for themselves, thinking of Allah thoughts that were not true, the guess of ignorance, saying: 'Have we any say in the affair' Say: 'The entire affair belongs to Allah' They conceal in themselves what they do not disclose to you. They say: 'If we had any say in the affair we should not have been killed here' Say: 'Had you stayed in your homes, those of you for whom slaying was written would have come out to their (death) beds so that Allah might try what was in your chests and that He will examine what is in your hearts' And Allah knows the innermost of the chests. 154 Those of you who turned back on the day the two hosts Met,-it was Satan who caused them to fail, because of some (evil) they had done. But Allah Has blotted out (their fault): For Allah is Oft-Forgiving, Most Forbearing. 155
