Assuredly We vouchsafed the Book unto Musa; so be thou not in doubt in thy receiving it. And We appointed it to be a guidance unto the Children of Is'rail. 23 When they persevered and firmly believed Our revelations We appointed learned men among them who guided them by Our command. 24 Surely your Lord will judge between them on the day of resurrection concerning that wherein they differ. 25 Is it not a guidance for them (to observe) how many generations We destroyed before them, amid whose dwelling places they do walk? Lo! therein verily are portents! Will they not then heed? 26 Do they not see that We drive the rain towards a land that is dry, then grow grain from it which their cattle and they themselves eat? Will they not see even then? 27 They say: "When will this decision be, if ye are telling the truth?" 28 Say, "On the Day of Judgement it will be of no benefit to those who were bent on denying the truth, if they [then] believe! They will be granted no respite." 29 Turn away from them and wait. They are, also, waiting. 30
