We did indeed aforetime give the Book to Moses: be not then in doubt of its reaching (thee): and We made it a guide to the Children of Israel. 23 We appointed some of the Israelites as leaders for their exercising patience to guide the others to Our commands. They had firm belief in Our revelations. 24 Surely thy Lord will distinguish between them on the Resurrection Day, touching that whereon they were at variance. 25 Does it not guide them [to see] how many generations We destroyed before them, among whose ruined dwellings they now walk about? There truly are signs in this -- will they not listen? 26 Have they not seen how We lead the water to the barren land and therewith bring forth crops whereof their cattle eat, and they themselves? Will they not then see? 27 And they say: When will this Decision arrive if ye are truthtellers? 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 Wherefore turn aside thou from them, and await; verily they are awaiting. 30
