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 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 for what they have associated with Allah of which He had not sent down [any] authority. And their refuge will be the Fire, and wretched is the residence of the wrongdoers. 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 ۞ 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 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 the two hosts met, it was the Satan who made them slip because of something they had earned; and of a surety Allah hath pardoned them. Verily, Allah is Forgiving, Forbearing. 155
