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 appointed, from amongst them, leaders guiding others by Our command, when they had persevered, and of Our signs they were convinced. 24 Surely your Lord will decide between them about what they were at variance, on the Day of Resurrection. 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 And they say, "When will this judgement come, if you are telling 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 Therefore turn away from them and wait – indeed they too have to wait. 30
