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 God has been true in His promise towards you when you blasted them by His leave; until you lost heart, and quarrelled about the matter, and were rebellious, after He had shown you that you longed for. Some of you there are that desire this world, and some of you there are desire the next world. Then He turned you from them, that He might try you; and He has pardoned you; and God is bounteous to the believers. 152 ۞ When you were running away and did not look back at anyone, while the Messenger was calling to you from behind, He paid you back with one sorrow after another, so that you might not grieve for what you lost, nor for what befell you. God 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 Those of you who turned away on the day the two hosts met [in battle] were made to slip by Satan on account of some of their deeds. But God has pardoned them: God is forgiving and forbearing. 155
