Believers, if you obey those who disbelieve they will turn you upon your heels and you will turn to be losers. 149 In fact, Allah is your Master; and He is the Best Supporter. 150 We shall cast terror into the hearts of those who disbelieve, because they joined others in worship with Allah, for which He had sent no authority; their abode will be the Fire and how evil is the abode of the Zalimun (polytheists and 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 ۞ When you were going up, not twisting about for anyone, and the Messenger was calling you in your rear; so He rewarded you with grief on grief that you might not sorrow for what escaped you neither for what smote you; and God is aware of the things you do. 153 Then, after sorrow, He sent down unto you a security - slumber coming over a section of you; while another section, concerned about themselves, bethought of Allah unjustly: the thought of paganism. They said: have we aught at all of the affair? Say thou: the affair is wholly Allah's. They hide within themselves that which they disclose not unto thee, saying: had we aught of the affair, we would not have been slain here. Say thou: had ye stayed in your houses, even then those decreed to be slain would surely have gone forth to their places of slaughter; and this happened in order that he might prove that which was in your breasts, and purge that which was in your hearts; and Allah is Knower of that which is in the breasts. 154 Those of you who turned away on the day when the two armies met must have been seduced by satan on account of some of what they had earned. But Allah has pardoned them. He is Forgiving and Clement. 155
