Believers, if you yield to those who deny the truth, they will cause you to turn back on your heels and you will turn into losers. 149 No; but God is your Protector, and He is the best of helpers. 150 We will cast terror into the hearts of those who have denied the Truth since they have associated others with Allah in His divinity - something for which He has sent down no sanction. The Fire is their abode; how bad the resting place of the wrong-doers will be! 151 God certainly fulfilled His promise to you when you were fighting the unbelievers, by His permission. Even after We showed you what you wanted, you began to lose courage, started quarreling with each other, and disobeyed God's orders. Some of you want worldly gains and others of you want rewards in the hereafter. Then He let you face defeat in order to test you. However, He forgave you. God is Gracious to the believers. 152 ۞ And recall what time ye were running off and would not look back on any one, albeit the apostle in your rear was calling unto you. Wherefore He caused sorrow to overtake you for sorrow, that ye might not grieve for that which ye might lose nor for that which might befall you. And Allah is Aware of that which ye work. 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 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
