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 But Allah is your Protector, 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 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 ۞ When you were running away and did not look back at anyone, while the Messenger was calling to you from behind, He paid you back with one sorrow after another, so that you might not grieve for what you lost, nor for what befell you. God is aware of what you do. 153 Then after distress, He sent down upon you security [in the form of] drowsiness, overcoming a faction of you, while another faction worried about themselves, thinking of Allah other than the truth - the thought of ignorance, saying, "Is there anything for us [to have done] in this matter?" Say, "Indeed, the matter belongs completely to Allah." They conceal within themselves what they will not reveal to you. They say, "If there was anything we could have done in the matter, some of us would not have been killed right here." Say, "Even if you had been inside your houses, those decreed to be killed would have come out to their death beds." [It was] so that Allah might test what is in your breasts and purify what is in your hearts. And Allah is Knowing of that within the breasts. 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
