O believers, if you obey the unbelievers they will turn you upon your heels, and you will turn about, losers. 149 Nay, Allah is your protector, and He is the best of helpers. 150 We shall strike terror into the hearts of unbelievers for ascribing compeers to God for which He has sent down no sanction. Hell is their residence, the evil abode of the unjust. 151 And Allah had assuredly made good His promise unto you when ye were extirpating them by His leave, until when ye flagged and ye disagreed about the command and ye disobeyed after He had shewn you that for which ye longed. Of you some desired the world and of you some desired the Hereafter, wherefore He turned you away from them that he might prove you; and of a surety He hath pardoned you. And Allah is Gracious unto the believers. 152 ۞ [Remember] when you [fled and] climbed [the mountain] without looking aside at anyone while the Messenger was calling you from behind. So Allah repaid you with distress upon distress so you would not grieve for that which had escaped you [of victory and spoils of war] or [for] that which had befallen you [of injury and death]. And Allah is [fully] Acquainted with what you 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 away on the day the two hosts met [in battle] were made to slip by Satan on account of some of their deeds. But God has pardoned them: God is forgiving and forbearing. 155
