Assuredly We vouchsafed the Book unto Musa; so be thou not in doubt in thy receiving it. And We appointed it to be a guidance unto the Children of Is'rail. 23 And We made of them Imams to guide by Our command when they were patient, and they were certain of Our communications. 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 point out to them the right way, how many of the generations, in whose abodes they go about, did We destroy before them? Most surely there are signs in this; will they not then hear? 26 Have they not seen how We lead the water to the barren land and therewith bring forth crops whereof their cattle eat, and they themselves? Will they not then see? 27 They also ask: 'When will this Opening come, if what you say is true' 28 Tell them: “If the unbelievers were to believe on the Day of Judgement that will not avail them. For then they will be granted no respite.” 29 Turn away from them and wait. They are, also, waiting. 30
