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 Friend, and He is the Best of helpers. 150 We shall cause terror to enter the hearts of the faithless for their considering things equal to God without authoritative evidence. Their abode will be fire, a terrible dwelling for the unjust. 151 God certainly fulfilled His promise to you when you were fighting the unbelievers, by His permission. Even after We showed you what you wanted, you began to lose courage, started quarreling with each other, and disobeyed God's orders. Some of you want worldly gains and others of you want rewards in the hereafter. Then He let you face defeat in order to test you. However, He forgave you. God is Gracious to the believers. 152 ۞ When you were going up, not twisting about for anyone, and the Messenger was calling you in your rear; so He rewarded you with grief on grief that you might not sorrow for what escaped you neither for what smote you; and God is aware of the things you do. 153 Then, after sorrow He sent down peace [of mind] upon you in the shape of drowsiness that overcame some of you, but there were others who were anxious only about themselves. They entertained false notions about God, like the notions of the days of ignorance. "Have we any say in the matter?" they asked. Say to them, "All is in the hands of God." They conceal in their hearts what they would not reveal to you. They say, "Had we had any say in the matter, none of us would have been killed here." Say to them, "Had you stayed in your homes, those whose death had been decreed would nevertheless have gone forth to the places where they were destined to die." And all this befell you so that God might test what is in your minds. And in order to purify what was in your hearts. For God is aware of your innermost thoughts. 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
