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 Surely your Lord will judge between them on the day of resurrection concerning that wherein they 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 And do they not see that We send the water to the barren land and produce crops with it, so their animals and they themselves eat from it? So do they not perceive? 27 But they answer: "When will that final decision take place, if what you [believers] say is true?" 28 Say: "On the Day of Al-Fath (Decision), no profit will it be to those who disbelieve if they (then) believe! Nor will they be granted a respite." 29 So (leave them to themselves and) turn away from them and wait; they too are waiting. 30
