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 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 to the barren land and cause crops to grow which they and their cattle consume? Why, then, they will not see? 27 They say: "When will this decision be, if ye 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
