Believers, if you obey the unbelievers, they will turn you back to disbelief and you will become lost. 149 But: Allah is your Friend, and He is the Best of helpers. 150 We will cast terror into the hearts of those who disbelieve for what they have associated with Allah of which He had not sent down [any] authority. And their refuge will be the Fire, and wretched is the residence of the wrongdoers. 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 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 Indeed those of you who turned back on the day when the two armies met – for it was the devil who caused them to waver, because of some of their deeds; and undoubtedly Allah has forgiven them; indeed Allah is Oft Forgiving, Most Forbearing. 155
