O you who have believed, if you obey those who disbelieve, they will turn you back on your heels, and you will [then] become losers. 149 God is your Guardian and the best Helper. 150 We will strike awe into the hearts of those who deny the truth, because they have associated partners with God, for which He has sent down no authority. Their abode shall be the Fire, and evil indeed is the abode of the wrongdoers. 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 ye climbed (the hill) and paid no heed to anyone, while the messenger, in your rear, was calling you (to fight). Therefor He rewarded you grief for (his) grief, that (He might teach) you not to sorrow either for that which ye missed or for that which befell you. Allah is Informed of what ye do. 153 After (the excitement) of the distress, He sent down calm on a band of you overcome with slumber, while another band was stirred to anxiety by their own feelings, Moved by wrong suspicions of Allah-suspicions due to ignorance. They said: "What affair is this of ours?" Say thou: "Indeed, this affair is wholly Allah's." They hide in their minds what they dare not reveal to thee. They say (to themselves): "If we had had anything to do with this affair, We should not have been in the slaughter here." Say: "Even if you had remained in your homes, those for whom death was decreed would certainly have gone forth to the place of their death"; but (all this was) that Allah might test what is in your breasts and purge what is in your hearts. For Allah knoweth well the secrets of your hearts. 154 Those of you who turned away the day the two hosts encountered -- Satan made them slip for somewhat they had earned; but God has pardoned them; God is All-forgiving, All-clement. 155
