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 Verily thy Lord will judge between them on the Day of Judgment, in the matters wherein they differ (among themselves) 25 Is it not a guidance to them, how many generations We destroyed before them in whose dwelling-places they walk? Surely in that are signs; what, will they not hear? 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 also ask: 'When will this Opening come, if what you say is true' 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 So turn away from them and wait. Indeed, they are waiting. 30
