We did indeed aforetime give the Book to Moses: be not then in doubt of its reaching (thee): and We made it a guide to 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 Indeed, your Lord will judge between them on the Day of Resurrection concerning that over which they used to differ. 25 Does it not point out to them the right way, how many of the generations, in whose abodes they go about, did We destroy before them? Most surely there are signs in this; will they not then hear? 26 Have they not seen that We drive the water to the barren land and cause crops to grow which they and their cattle consume? Why, then, they will not see? 27 Yet they say: "When will this decree come, if you speak the truth?" 28 Tell them: “If the unbelievers were to believe on the Day of Judgement that will not avail them. For then they will be granted no respite.” 29 and then leave them alone, and wait [for the truth to unfold as] they, behold, are waiting. 30
