Believers, if you obey the unbelievers, they will turn you back to disbelief and you will become lost. 149 Nay! Allah is your Patron and He is the best of the helpers. 150 We will cast into the hearts of the unbelievers terror, for that they have associated with God that for which He sent down never authority; their lodging shall be the Fire; evil is the lodging of the evildoers. 151 Allah has been true in His promise towards you when you routed them by His leave, until you lost heart, and quarreled about the matter, and disobeyed, after He had shown you that which you loved. Some among you wanted the world, and some among you wanted the Everlasting Life. Then He made you turn away from them in order to test you. But He has forgiven you, for Allah is Bounteous to the believers. 152 ۞ When you were leaving, unconcerned without turning to look back at anyone, and from another group Our Noble Messenger was calling you (to fight); so He gave you sorrow in lieu of sorrow, and then forgave you so that you do not grieve over what has been lost or over the calamity that befell you; and Allah is Well 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 (As for) those of you who turned back on the day when the two armies met, only the Shaitan sought to cause them to make a slip on account of some deeds they had done, and certainly Allah has pardoned them; surely Allah is Forgiving, Forbearing. 155
