O Ye who believe! if ye obey those who disbelieve, they will send you back on your heels, and ye will turn back losers. 149 Nay! Allah is your Patron and He is the best of the 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 AND, INDEED, God made good His promise unto you when, by His leave, you were about to destroy your foes - until the moment when you lost heart and acted contrary to the [Prophet's] command, and disobeyed after He had brought you within view of that [victory] for which you were longing. There were among you such as cared for this world [alone,] just as there were among you such as cared for the life to come: whereupon, in order that He might put you to a test, He prevented you from defeating your foes. But now He has effaced your sin: for God is limitless in His bounty unto the believers. 152 ۞ Behold! ye were climbing up the high ground, without even casting a side glance at any one, and the Messenger in your rear was calling you back. There did Allah give you one distress after another by way of requital, to teach you not to grieve for (the booty) that had escaped you and for (the ill) that had befallen you. For Allah is well aware of all that ye do. 153 Then after grief, He sent down a peaceful slumber (calm), which engulfed a group among you – and another party kept fearing for their own lives, thinking wrongfully of Allah – like the thoughts of ignorance; they say, “Do we have any authority in this matter?” Say (O dear Prophet Mohammed – peace and blessings be upon him), “All authority lies only with Allah”; they hide in their hearts what they do not reveal to you; they say, “Had we any control, we would not have been slain here”; say, “Even if you had been in your houses, those destined to be slain would have come forth to their places of slaying; and in order that Allah may test what is in your breasts and reveal whatever is in your hearts”; and Allah knows well what lies within the hearts. 154 Those of you who turned back on the day the two hosts Met,-it was Satan who caused them to fail, because of some (evil) they had done. But Allah Has blotted out (their fault): For Allah is Oft-Forgiving, Most Forbearing. 155
