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 among them leaders guiding by Our command, when they endured patiently, and had sure faith in Our signs. 24 On the Day of Resurrection your Lord will distinguish between them that on which they varied. 25 Is it not a guidance to them, how many generations We destroyed before them in whose dwelling places they walk? Surely, in this there are signs. Will they not then hear! 26 Observe they not that We drive water unto a land bare, and bring forth therewith crops whereof their cattle and they themselves eat? Will they not therefore be enlightened? 27 They say: "When will this decision be, if ye are telling the truth?" 28 Say: "On the Day of the Final Decision, their [newly-found] faith will be of no use to those who [in their lifetime] were bent on denying the truth, nor will they be granted respite!" 29 So withdraw from them (O Muhammad), and await (the event). Lo! they (also) are awaiting (it). 30
