Believers, if you yield to those who deny the truth, they will cause you to turn back on your heels and you will turn into losers. 149 In fact, Allah is your Master; and He is the Best Supporter. 150 We shall cast terror into the hearts of those who disbelieve because they ascribe unto Allah partners, for which no warrant hath been revealed. Their habitation is the Fire, and hapless the abode of the wrong-doers. 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 ۞ Recall when you were fleeing without casting even a side glance at anyone, and the Messenger was calling out to you from the rear. Then Allah requited you by inflicting grief after grief upon you so as to instruct you neither to grieve for the losses you might suffer nor for the afflictions that might befall you. Allah knows all that 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 (As for) those of you who turned back on the day when the two armies met, only the Shaitan sought to cause them to make a slip on account of some deeds they had done, and certainly Allah has pardoned them; surely Allah is Forgiving, Forbearing. 155
