Believers, if you obey the unbelievers, they will turn you back to disbelief and you will become lost. 149 No, indeed! it is God who is your protector: 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 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 ran off precipitately and did not wait for any one, and the Apostle was calling you from your rear, so He gave you another sorrow instead of (your) sorrow, so that you might not grieve at what had escaped you, nor (at) what befell you; and Allah is aware of what you 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 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
