Verily We gave Moses the Book; so be not in doubt about his having received it; and We made it a guidance for 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 Do they not see how We drive the water to the parched lands and bring forth therefrom crops from which their cattle and themselves eat? Will they not see! 27 They say: “If you are truthful, (tell us) when will the Judgement come?” 28 Say: 'On the Day of Opening the faith of the unbelievers will not benefit them, nor shall they be respited' 29 Therefore turn away from them and wait, surely they too are waiting. 30
