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 Has it not become clear to them how many generations We destroyed before them, [as] they walk among their dwellings? Indeed in that are signs; then do they not hear? 26 Observe they not that We drive water unto a land bare, and bring forth therewith crops whereof their cattle and they themselves eat? Will they not therefore be enlightened? 27 They say, "If what you say is true, when will the final triumph come?" 28 Say: "On the Day of the Final Decision, their [newly-found] faith will be of no use to those who [in their lifetime] were bent on denying the truth, nor will they be granted respite!" 29 So (leave them to themselves and) turn away from them and wait; they too are waiting. 30
