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 appointed, from amongst them, leaders guiding others by Our command, when they had persevered, and of Our signs they were convinced. 24 Surely your Lord will decide between them about what they were at variance, on the Day of Resurrection. 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 Have they not seen that We drive water to the parched land, thereby bringing forth crops which they and their cattle eat? Are they unable to see? 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 Therefore turn away from them and wait as they are waiting. 30
