O you who have believed, if you obey those who disbelieve, they will turn you back on your heels, and you will [then] become losers. 149 God is your Guardian and the best Helper. 150 We will cast terror into the hearts of those who disbelieve, because they set up with Allah that for which He has sent down no authority, and their abode is the fire, and evil is the abode of the unjust. 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 ۞ (Believers remember) when you were fleeing without even glancing to either side even though the Messengers were calling you back, God made you suffer sorrow upon sorrow to make you forget your grief of what you had lost and the injuries you had suffered. God is Well-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 Lo! those of you who turned back on the day when the two hosts met, Satan alone it was who caused them to backslide, because of some of that which they have earned. Now Allah hath forgiven them. Lo! Allah is Forgiving, Clement. 155
