Believers, if you obey the unbelievers, they will turn you back to disbelief and you will become lost. 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 And God made good His promise to you when by His leave you were about to destroy your foes, but then your courage failed you and you disagreed among yourselves [concerning the Prophet's direction] and disobeyed it, after He had brought you within sight of what you wished for, some of you desired the goods of this world and some of you desired the Hereafter, then in order that He might put you to the test, He prevented you from defeating your foes. But now He has pardoned you: God is most gracious to the believers. 152 ۞ Behold! ye were climbing up the high ground, without even casting a side glance at any one, and the Messenger in your rear was calling you back. There did Allah give you one distress after another by way of requital, to teach you not to grieve for (the booty) that had escaped you and for (the ill) that had befallen you. For Allah is well aware of all that ye do. 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 (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
