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 And when they became steadfast and believed firmly in Our revelations, We appointed from among them leaders who guided by Our command. 24 On the Day of Resurrection your Lord will distinguish between them that on which they varied. 25 Was it not a lesson for them, (the unbelievers), that We destroyed the many generations living before them among whose ruined dwellings they are now walking. In this there is many evidence (of the truth). Will 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 They also ask: 'When will this Opening come, if what you say is true' 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 So turn away from them and wait. Indeed, they are waiting. 30
