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 Your Lord will issue His decree about their (believers and disbeliever's) differences on the Day of Judgment. 25 Does it not teach them a lesson, how many generations We destroyed before them, in whose dwellings they (now) go to and fro? Verily in that are Signs: Do they not then listen? 26 Have they not seen how We drive water (rain clouds) to the dry land without any vegetation, and therewith bring forth crops providing food for their cattle and themselves? Will they not then see? 27 They also ask: 'When will this Opening come, if what you say is true' 28 Say thou: on the day of the Decision their belief will not profit those who have disbelieved; nor will they be respited. 29 So (leave them to themselves and) turn away from them and wait; they too are waiting. 30
