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 We appointed some of the Israelites as leaders for their exercising patience to guide the others to Our commands. They had firm belief in Our revelations. 24 Surely 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 Do they not see how We drive the water to the parched lands and bring forth therefrom crops from which their cattle and themselves eat? Will they not see! 27 But they answer: "When will that final decision take place, if what you [believers] say is true?" 28 Say: 'On the Day of Opening the faith of the unbelievers will not benefit them, nor shall they be respited' 29 So (leave them to themselves and) turn away from them and wait; they too are waiting. 30
