O you who have believed, if you obey those who disbelieve, they will turn you back on your heels, and you will [then] become losers. 149 Nay, Allah is your Maula (Patron, Lord, Helper and Protector, etc.), and He is the Best of helpers. 150 We shall cause terror to enter the hearts of the faithless for their considering things equal to God without authoritative evidence. Their abode will be fire, a terrible dwelling for the unjust. 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 ۞ Remember, as you were rushing up (the hill) without turning back to look, though the Prophet was calling you from the rear, He requited you with anguish for an anguish that you do not fret for missed opportunity and what befell you, for God is aware of all that 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
