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 appointed from among them leaders guiding by Our command, when they endured patiently, and had sure faith in Our signs. 24 Surely thy Lord will distinguish between them on the Resurrection Day, touching that whereon they were at variance. 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 that We drive the water [in clouds] to barren land and bring forth thereby crops from which their livestock eat and [they] themselves? Then do they not see? 27 They also ask: 'When will this Opening come, if what you say is true' 28 Say: "On the Day of Decision, no profit will it be to Unbelievers if they (then) believe! nor will they be granted a respite." 29 So turn away from them, and wait: they too are waiting. 30
