Verily We gave Moses the Book; so be not in doubt about his having received it; and We made it a guidance for the children of Israel. 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 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 And do they not see that We do drive rain to parched soil (bare of herbage), and produce therewith crops, providing food for their cattle and themselves? Have they not the vision? 27 They say, "If what you say is true, when will the final triumph come?" 28 Say: On the day of judgment the faith of those who (now) disbelieve will not profit them, nor will they be respited. 29 Wherefore turn aside thou from them, and await; verily they are awaiting. 30
