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 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 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 And they say: When cometh this victory (of yours) if ye are truthful? 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 turn thou away from them, and wait; they too are waiting. 30
