O you who believe! If you obey those who disbelieve, they will send you back on your heels, and you will turn back (from Faith) as losers. 149 But Allah is your Sponsor. He is the Best of victors. 150 We shall cast terror into the hearts of those who disbelieve, because they joined others in worship with Allah, for which He had sent no authority; their abode will be the Fire and how evil is the abode of the Zalimun (polytheists and wrong-doers). 151 And Allah had certainly fulfilled His promise to you when you were killing the enemy by His permission until [the time] when you lost courage and fell to disputing about the order [given by the Prophet] and disobeyed after He had shown you that which you love. Among you are some who desire this world, and among you are some who desire the Hereafter. Then he turned you back from them [defeated] that He might test you. And He has already forgiven you, and Allah is the possessor of bounty for the believers. 152 ۞ And recall what time ye were running off and would not look back on any one, albeit the apostle in your rear was calling unto you. Wherefore He caused sorrow to overtake you for sorrow, that ye might not grieve for that which ye might lose nor for that which might befall you. And Allah is Aware of that which ye work. 153 Then, after this woe, He sent down upon you a sense of security, an inner calm which enfolded some of you, whereas the others, who cared mainly for themselves, entertained wrong thoughts about God - thoughts of pagan ignorance - saying, "Did we, then, have any power of decision [in this matter]?" Say: "Verily, all power of decision does rest with God" - [but as for them,] they are trying to conceal within themselves that [weakness of faith] which they would not reveal unto thee, [O Prophet, by] saying, "If we had any power of decision, we would not have left so many dead behind." Say [unto them]: "Even if you had remained in your homes, those [of you] whose death had been ordained would indeed have gone forth to the places where they were destined to lie down." And [all this befell you] so that God might put to a test all that you harbour in your bosoms, and render your innermost hearts pure of all dross: for God is aware of what is in the hearts [of men]. 154 Indeed, those of you who turned back on the day the two armies met, it was Satan who caused them to slip because of some [blame] they had earned. But Allah has already forgiven them. Indeed, Allah is Forgiving and Forbearing. 155
