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 When they persevered and firmly believed Our revelations We appointed learned men among them who guided them by Our command. 24 On the Day of Resurrection your Lord will distinguish between them that on which they varied. 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 And do they not see that We do drive rain to parched soil (bare of herbage), and produce therewith crops, providing food for their cattle and themselves? Have they not the vision? 27 Yet they say: "When will this decree come, if you speak the truth?" 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 withdraw from them (O Muhammad), and await (the event). Lo! they (also) are awaiting (it). 30
