Believers! If you follow those who deny the Truth, they will drive you back on your heels, and you will turn about, losers. 149 But Allah is your Protector, and He is the best of helpers. 150 We shall cause terror to enter the hearts of the faithless for their considering things equal to God without authoritative evidence. Their abode will be fire, a terrible dwelling for the unjust. 151 And Allah did indeed fulfil His Promise to you when you were killing them (your enemy) with His Permission; until (the moment) you lost your courage and fell to disputing about the order, and disobeyed after He showed you (of the booty) which you love. Among you are some that desire this world and some that desire the Hereafter. Then He made you flee from them (your enemy), that He might test you. But surely, He forgave you, and Allah is Most Gracious to the believers. 152 ۞ And when you were going up, and paid no heed for anyone, and the Messenger was calling you from behind; so He rewarded you with grief upon grief that you might not sorrow for what escaped you neither for what smote you. And Allah is Aware of 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 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
