Believers, if you obey those who disbelieve they will turn you upon your heels and you will turn to be losers. 149 God is your Guardian and the best Helper. 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 leaving, unconcerned without turning to look back at anyone, and from another group Our Noble Messenger was calling you (to fight); so He gave you sorrow in lieu of sorrow, and then forgave you so that you do not grieve over what has been lost or over the calamity that befell you; and Allah is Well Aware of what you do. 153 Then, after inflict-ing this grief, He sent down an inner peace upon you - a sleep which overtook some of you. Those who were concerned merely about themselves, entertaining false notions about Allah - the notions of the Age of Ignorance - asked: 'Have we any say in the matter?' Tell them: 'Truly, all power of decision rests solely with Allah.' Indeed, they conceal in their hearts what they would not reveal to you, saying: 'If we had any power of decision, we would not have been slain here.' Say: 'Even if you had been in your houses, those for whom slaying had been appointed would have gone forth to the places where they were to be slain.' And all this happened so that Allah might test your secret thoughts and purge your hearts of all impurities. Allah knows well what is in the breasts of men. 154 Those of you who turned back on the day the two hosts met (i.e. the battle of Uhud), it was Shaitan (Satan) who caused them to backslide (run away from the battlefield) because of some (sins) they had earned. But Allah, indeed, has forgiven them. Surely, Allah is Oft-Forgiving, Most Forbearing. 155
