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 When they persevered and firmly believed Our revelations We appointed learned men among them who guided them by Our command. 24 Surely thy Lord will distinguish between them on the Resurrection Day, touching that whereon they were at variance. 25 Is it not a guidance for them, how many generations We have destroyed before them in whose dwellings they do walk about? Verily, therein indeed are signs. Would 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 They say: "When will this Al-Fath (Decision) be (between us and you, i.e. the Day of Resurrection), if you are telling the truth?" 28 Say, "On the day of the final triumph, the faith of the disbelievers will be of no avail to them, nor will they be given any respite". 29 and then leave them alone, and wait [for the truth to unfold as] they, behold, are waiting. 30
