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 from among them leaders guiding by Our command when they were patient and [when] they were certain of Our signs. 24 Your Lord will issue His decree about their (believers and disbeliever's) differences on the Day of Judgment. 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 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 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 Therefore turn away from them, and wait, they are waiting. 30
