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 Your Lord will issue His decree about their (believers and disbeliever's) differences on the Day of Judgment. 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 Have they not seen how We drive water (rain clouds) to the dry land without any vegetation, and therewith bring forth crops providing food for their cattle and themselves? Will they not then see? 27 And they say, "When will this judgement come, if you are telling the truth?" 28 Say: 'On the Day of Opening the faith of the unbelievers will not benefit them, nor shall they be respited' 29 So turn thou away from them, and wait; they too are waiting. 30
