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 God has been true in His promise towards you when you blasted them by His leave; until you lost heart, and quarrelled about the matter, and were rebellious, after He had shown you that you longed for. Some of you there are that desire this world, and some of you there are desire the next world. Then He turned you from them, that He might try you; and He has pardoned you; and God is bounteous to the 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 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
