Believers, if you obey the unbelievers, they will turn you back to disbelief and you will become lost. 149 But Allah is your Protector, and He is the Best of Helpers. 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 And Allah had certainly fulfilled His promise to you when you were killing the enemy by His permission until [the time] when you lost courage and fell to disputing about the order [given by the Prophet] and disobeyed after He had shown you that which you love. Among you are some who desire this world, and among you are some who desire the Hereafter. Then he turned you back from them [defeated] that He might test you. And He has already forgiven you, and Allah is the possessor of bounty for the believers. 152 ۞ Remember, as you were rushing up (the hill) without turning back to look, though the Prophet was calling you from the rear, He requited you with anguish for an anguish that you do not fret for missed opportunity and what befell you, for God is aware of all that you do, 153 Then He sent down upon you, after grief, security -- a slumber overcoming a party of you; and a party themselves had grieved, thinking of God thoughts that were not true such as the pagans thought, saying, 'Have we any part whatever in the affair?' Say: 'The affair belongs to God entirely.' They were concealing in their hearts that they show not to thee, saying, 'Ah, if we had had a part in the affair, never would we have been slain here.' Say: 'Even if you had been in your houses, those for whom slaying was appointed would have sallied forth unto their last couches'; and that God might try what was in your breasts, and that He might prove what was in your hearts; and God knows the thoughts in the breasts. 154 Those of you who turned away the day the two hosts encountered -- Satan made them slip for somewhat they had earned; but God has pardoned them; God is All-forgiving, All-clement. 155
