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 Verily, your Lord will judge between them on the Day of Resurrection, concerning that wherein they used to differ. 25 And did they not obtain guidance by the fact that We did destroy many generations before them, so now they walk in their houses? Indeed in this are signs; so do they not heed? 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: "When will this decision be, if ye 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 Therefore turn away from them and wait as they are waiting. 30
