Indeed, We gave Moses the Book; so he not in doubt concerning the encounter with him; and We appointed it for a guidance to the Children of Israel. 23 We appointed leaders from among them, guiding by Our command when they were steadfast and when they had firm faith in Our signs. 24 On the Day of Resurrection your Lord will distinguish between them that on which they varied. 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 Have they not seen that We drive the water [in clouds] to barren land and bring forth thereby crops from which their livestock eat and [they] themselves? Then do they not see? 27 And they say: When will this Decision arrive if ye are truthtellers? 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 and then leave them alone, and wait [for the truth to unfold as] they, behold, are waiting. 30
