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 And We appointed from among them leaders guiding by Our command, when they endured patiently, and had sure faith in Our signs. 24 Surely thy Lord will distinguish between them on the Resurrection Day, touching that whereon they were at variance. 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 Opening the faith of the unbelievers will not benefit them, nor shall they be respited' 29 and then leave them alone, and wait [for the truth to unfold as] they, behold, are waiting. 30
