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 But God is your protector, and He is the best of helpers. 150 We will throw terror into the hearts of those who disbelieve. For that they have associated with Allah that which He did not send down for a proof. Fire shall be their home, evil indeed is the dwellingplace of the harmdoers. 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 ۞ When you were going up, not twisting about for anyone, and the Messenger was calling you in your rear; so He rewarded you with grief on grief that you might not sorrow for what escaped you neither for what smote you; and God is aware of the things 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 Behold, as for those of you who turned away [from their duty] on the day when the two hosts met in battle - Satan caused them to stumble only by means of something that they [themselves] had done. But now God has effaced this sin of theirs: verily, God is much-forgiving, forbearing. 155
