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 And We made from among them leaders guiding by Our command when they were patient and [when] they were certain of Our signs. 24 Your Lord will issue His decree about their (believers and disbeliever's) differences on the Day of Judgment. 25 Is it not a guidance for them, how many generations We have destroyed before them in whose dwellings they do walk about? Verily, therein indeed are signs. Would they not then listen? 26 Have they not seen how We drive the water to the dry land and bring forth crops therewith whereof their cattle and themselves eat? What, will they not see? 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 turn away from them, and wait: they too are waiting. 30
