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 when they became steadfast and believed firmly in Our revelations, We appointed from among them leaders who guided by Our command. 24 On the Day of Resurrection your Lord will distinguish between them that on which they varied. 25 Did they not find guidance in the many generations We had destroyed before them, over whose dwellings they (now) walk? There were indeed signs in this. Will they even then not listen? 26 Have they not seen that We drive water to the parched land, thereby bringing forth crops which they and their cattle eat? Are they unable to 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 So turn thou away from them, and wait; they too are waiting. 30
