O believers, if you listen to the infidels they will make you turn your backs, and you will be the losers. 149 But Allah is your Protector, and He is the Best of Helpers. 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 AND, INDEED, God made good His promise unto you when, by His leave, you were about to destroy your foes - until the moment when you lost heart and acted contrary to the [Prophet's] command, and disobeyed after He had brought you within view of that [victory] for which you were longing. There were among you such as cared for this world [alone,] just as there were among you such as cared for the life to come: whereupon, in order that He might put you to a test, He prevented you from defeating your foes. But now He has effaced your sin: for God is limitless in His bounty unto the believers. 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 sorrow He sent down security upon you, a calm coming upon a party of you, and (there was) another party whom their own souls had rendered anxious; they entertained about Allah thoughts of ignorance quite unjustly, saying: We have no hand in the affair. Say: Surely the affair is wholly (in the hands) of Allah. They conceal within their souls what they would not reveal to you. They say: Had we any hand in the affair, we would not have been slain here. Say: Had you remained in your houses, those for whom slaughter was ordained would certainly have gone forth to the places where they would be slain, and that Allah might test what was in your breasts and that He might purge what was in your hearts; and Allah knows what is in the 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
