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 thy Lord will distinguish between them on the Resurrection Day, touching that whereon they were at variance. 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 Are they not aware that it is We who drive the rain onto dry land devoid of herbage, and thereby bring forth herbage of which their cattle and they themselves do eat? Can they not, then, see [the truth of resurrection]? 27 They also say, 'When shall be this Victory, if you speak truly?' 28 Tell them: “If the unbelievers were to believe on the Day of Judgement that will not avail them. For then they will be granted no respite.” 29 So (leave them to themselves and) turn away from them and wait; they too are waiting. 30
