Believers, if you obey those who disbelieve they will turn you upon your heels and you will turn to be losers. 149 In fact, Allah is your Master; and He is the Best Supporter. 150 We will cast into the hearts of the unbelievers terror, for that they have associated with God that for which He sent down never authority; their lodging shall be the Fire; evil is the lodging of the evildoers. 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 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 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
