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 When they persevered and firmly believed Our revelations We appointed learned men among them who guided them by Our command. 24 Surely your Lord will judge between them on the Day of Resurrection concerning that wherein they used to differ. 25 Is it not a guidance for them (to observe) how many generations We destroyed before them, amid whose dwelling places they do walk? Lo! therein verily are portents! Will they not then heed? 26 Observe they not that We drive water unto a land bare, and bring forth therewith crops whereof their cattle and they themselves eat? Will they not therefore be enlightened? 27 They say: "When will this Al-Fath (Decision) be (between us and you, i.e. the Day of Resurrection), if you are telling the truth?" 28 Say (unto them): On the day of the victory the faith of those who disbelieve (and who then will believe) will not avail them, neither will they be reprieved. 29 So (leave them to themselves and) turn away from them and wait; they too are waiting. 30
