O believers, if you listen to the infidels they will make you turn your backs, and you will be the losers. 149 God is your Guardian and the best Helper. 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 And Allah had assuredly made good His promise unto you when ye were extirpating them by His leave, until when ye flagged and ye disagreed about the command and ye disobeyed after He had shewn you that for which ye longed. Of you some desired the world and of you some desired the Hereafter, wherefore He turned you away from them that he might prove you; and of a surety He hath pardoned you. And Allah is Gracious unto the believers. 152 ۞ And when you were going up, and paid no heed for anyone, and the Messenger was calling you from behind; so He rewarded you with grief upon grief that you might not sorrow for what escaped you neither for what smote you. And Allah is Aware of what you do. 153 Then, after inflict-ing this grief, He sent down an inner peace upon you - a sleep which overtook some of you. Those who were concerned merely about themselves, entertaining false notions about Allah - the notions of the Age of Ignorance - asked: 'Have we any say in the matter?' Tell them: 'Truly, all power of decision rests solely with Allah.' Indeed, they conceal in their hearts what they would not reveal to you, saying: 'If we had any power of decision, we would not have been slain here.' Say: 'Even if you had been in your houses, those for whom slaying had been appointed would have gone forth to the places where they were to be slain.' And all this happened so that Allah might test your secret thoughts and purge your hearts of all impurities. Allah knows well what is in the breasts of men. 154 Lo! those of you who turned back on the day when the two hosts met, Satan alone it was who caused them to backslide, because of some of that which they have earned. Now Allah hath forgiven them. Lo! Allah is Forgiving, Clement. 155
