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 Into the hearts of those who are bent on denying the truth We shall cast dread in return for their ascribing divinity, side by side with God, to other beings - [something] for which He has never bestowed any warrant from on high; and their goal is the fire - and how evil that abode of evildoers! 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 ۞ When you ran off precipitately and did not wait for any one, and the Apostle was calling you from your rear, so He gave you another sorrow instead of (your) sorrow, so that you might not grieve at what had escaped you, nor (at) what befell 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 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
