O believers, if you listen to the infidels they will make you turn your backs, and you will be the losers. 149 God is your Guardian and the best Helper. 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 certainly Allah made good to you His promise when you slew them by His permission, until when you became weak-hearted and disputed about the affair and disobeyed after He had shown you that which you loved; of you were some who desired this world and of you were some who desired the hereafter; then He turned you away from them that He might try you; and He has certainly pardoned you, and Allah is Gracious to the believers. 152 ۞ And when you were going up, and paid no heed for anyone, and the Messenger was calling you from behind; so He rewarded you with grief upon grief that you might not sorrow for what escaped you neither for what smote you. And Allah is Aware of what you do. 153 Then, after sorrow, He sent down unto you a security - slumber coming over a section of you; while another section, concerned about themselves, bethought of Allah unjustly: the thought of paganism. They said: have we aught at all of the affair? Say thou: the affair is wholly Allah's. They hide within themselves that which they disclose not unto thee, saying: had we aught of the affair, we would not have been slain here. Say thou: had ye stayed in your houses, even then those decreed to be slain would surely have gone forth to their places of slaughter; and this happened in order that he might prove that which was in your breasts, and purge that which was in your hearts; and Allah is Knower of that which is in the breasts. 154 (As for) those of you who turned back on the day when the two armies met, only the Shaitan sought to cause them to make a slip on account of some deeds they had done, and certainly Allah has pardoned them; surely Allah is Forgiving, Forbearing. 155
