Believers! If you follow those who deny the Truth, they will drive you back on your heels, and you will turn about, losers. 149 But God is your protector, and He is the best of helpers. 150 Into the hearts of those who are bent on denying the truth We shall cast dread in return for their ascribing divinity, side by side with God, to other beings - [something] for which He has never bestowed any warrant from on high; and their goal is the fire - and how evil that abode of evildoers! 151 And Allah had assuredly made good His promise unto you when ye were extirpating them by His leave, until when ye flagged and ye disagreed about the command and ye disobeyed after He had shewn you that for which ye longed. Of you some desired the world and of you some desired the Hereafter, wherefore He turned you away from them that he might prove you; and of a surety He hath pardoned you. And Allah is Gracious unto the believers. 152 ۞ When ye climbed (the hill) and paid no heed to anyone, while the messenger, in your rear, was calling you (to fight). Therefor He rewarded you grief for (his) grief, that (He might teach) you not to sorrow either for that which ye missed or for that which befell you. Allah is Informed of what ye do. 153 Then, after sorrow, He sent down upon you safety. Slumber overtook a party, while another party cared only for themselves, thinking of Allah thoughts that were not true, the guess of ignorance, saying: 'Have we any say in the affair' Say: 'The entire affair belongs to Allah' They conceal in themselves what they do not disclose to you. They say: 'If we had any say in the affair we should not have been killed here' Say: 'Had you stayed in your homes, those of you for whom slaying was written would have come out to their (death) beds so that Allah might try what was in your chests and that He will examine what is in your hearts' And Allah knows the innermost of the chests. 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
