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 We appointed some of the Israelites as leaders for their exercising patience to guide the others to Our commands. They had firm belief in Our revelations. 24 Verily thy Lord! He shall decide between them on the Day of Judgment concerning that wherein they have been differing. 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 Observe they not that We drive water unto a land bare, and bring forth therewith crops whereof their cattle and they themselves eat? Will they not therefore be enlightened? 27 And they say, "When will be this conquest, if you should be truthful?" 28 Say thou: on the day of the Decision their belief will not profit those who have disbelieved; nor will they be respited. 29 Therefore turn away from them and wait as they are waiting. 30
