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 When they persevered and firmly believed Our revelations We appointed learned men among them who guided them by Our command. 24 Verily, your Lord will judge between them on the Day of Resurrection, concerning that wherein they used to differ. 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 say, "If what you say is true, when will the final triumph come?" 28 Say (unto them): On the day of the victory the faith of those who disbelieve (and who then will believe) will not avail them, neither will they be reprieved. 29 So turn aside from them (O Muhammad SAW) and await, verily they (too) are awaiting. 30
