Believers, if you yield to those who deny the truth, they will cause you to turn back on your heels and you will turn into losers. 149 God is your Guardian and the best Helper. 150 Soon shall We cast terror into the hearts of the Unbelievers, for that they joined companions with Allah, for which He had sent no authority: their abode will be the Fire: And evil is the home of the wrong-doers! 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 ۞ [Remember] when you [fled and] climbed [the mountain] without looking aside at anyone while the Messenger was calling you from behind. So Allah repaid you with distress upon distress so you would not grieve for that which had escaped you [of victory and spoils of war] or [for] that which had befallen you [of injury and death]. And Allah is [fully] Acquainted with 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 Lo! those of you who turned back on the day when the two hosts met, Satan alone it was who caused them to backslide, because of some of that which they have earned. Now Allah hath forgiven them. Lo! Allah is Forgiving, Clement. 155
