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 when they became steadfast and believed firmly in Our revelations, We appointed from among them leaders who guided by Our command. 24 Surely your Lord will judge between them on the Day of Resurrection concerning that wherein they used to differ. 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 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 And they say, "When will this judgement come, if you are telling the truth?" 28 Say: "On the Day of Al-Fath (Decision), no profit will it be to those who disbelieve if they (then) believe! Nor will they be granted a respite." 29 Wherefore turn aside thou from them, and await; verily they are awaiting. 30
