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 surely fulfilled His promise (of succour) when you were slaying them by His leave until the moment when you flagged and quarrelled among yourselves about the matter, and acted against the order of (the Prophet). Soon He showed you what you had intensely desired - for some among you sought this world and some of you sought the Next. Thereupon, in order to put you to a test He turned you away from your foes. Still He pardoned you after that for Allah is Bounteous to those who believe. 152 ۞ When you were leaving, unconcerned without turning to look back at anyone, and from another group Our Noble Messenger was calling you (to fight); so He gave you sorrow in lieu of sorrow, and then forgave you so that you do not grieve over what has been lost or over the calamity that befell you; and Allah is Well Aware of what you do. 153 Then after the distress, He sent down security for you. Slumber overtook a party of you, while another party was thinking about themselves (as how to save their ownselves, ignoring the others and the Prophet SAW) and thought wrongly of Allah - the thought of ignorance. They said, "Have we any part in the affair?" Say you (O Muhammad SAW): "Indeed the affair belongs wholly to Allah." They hide within themselves what they dare not reveal to you, saying: "If we had anything to do with the affair, none of us would have been killed here." Say: "Even if you had remained in your homes, those for whom death was decreed would certainly have gone forth to the place of their death," but that Allah might test what is in your breasts; and to Mahis that which was in your hearts (sins), and Allah is All-Knower of what is in (your) breasts. 154 Behold, as for those of you who turned away [from their duty] on the day when the two hosts met in battle - Satan caused them to stumble only by means of something that they [themselves] had done. But now God has effaced this sin of theirs: verily, God is much-forgiving, forbearing. 155
