Believers! If you follow those who deny the Truth, they will drive you back on your heels, and you will turn about, 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 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 ye climbed (the hill) and paid no heed to anyone, while the messenger, in your rear, was calling you (to fight). Therefor He rewarded you grief for (his) grief, that (He might teach) you not to sorrow either for that which ye missed or for that which befell you. Allah is Informed of what 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 Those of you who turned away the day the two hosts encountered -- Satan made them slip for somewhat they had earned; but God has pardoned them; God is All-forgiving, All-clement. 155
