O you who believe! if you obey those who disbelieve they will turn you back upon your heels, so you will turn back losers. 149 No; but God is your Protector, and He is the best of helpers. 150 Soon shall We cast terror into the hearts of the Unbelievers, for that they joined companions with Allah, for which He had sent no authority: their abode will be the Fire: And evil is the home of the wrong-doers! 151 And indeed Allah has proved true His promise to you, when you used to slay the disbelievers by His command; until the time you people lost courage and disputed about the order and disobeyed after Allah had shown you what pleases you; some of you desired the world, and some of you desired the Hereafter; thereafter He turned you away from them in order to test you; and undoubtedly He has forgiven you; and Allah is Most Munificent towards the Muslims. 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, after grief, He sent down security for you. As slumber did it overcome a party of you, while (the other) party, who were anxious on their own account, thought wrongly of Allah, the thought of ignorance. They said: Have we any part in the cause? Say (O Muhammad): The cause belongeth wholly to Allah. They hide within themselves (a thought) which they reveal not unto thee, saying: Had we had any part in the cause we should not have been slain here. Say: Even though ye had been in your houses, those appointed to be slain would have gone forth to the places where they were to lie. (All this hath been) in order that Allah might try what is in your breasts and prove what is in your hearts. Allah is Aware of what is hidden in the breasts (of men). 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
