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 On the Day of Resurrection your Lord will distinguish between them that on which they varied. 25 Does it not guide them [to see] how many generations We destroyed before them, among whose ruined dwellings they now walk about? There truly are signs in this -- will they not listen? 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 They say: "When will this decision be, if ye are telling the truth?" 28 Say, "On the day of the final triumph, the faith of the disbelievers will be of no avail to them, nor will they be given any respite". 29 Therefore turn away from them, and wait, they are waiting. 30
