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 made of them Imams to guide by Our command when they were patient, and they were certain of Our communications. 24 Lo! thy Lord will judge between them on the Day of Resurrection concerning that wherein they used to differ. 25 Is it not a guidance for them (to observe) how many generations We destroyed before them, amid whose dwelling places they do walk? Lo! therein verily are portents! Will they not then heed? 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 And they say: When will this judgment take place, If you are truthful? 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 turn away from them and wait. They too are waiting. 30
