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 Indeed, your Lord will judge between them on the Day of Resurrection concerning that over which they used to differ. 25 Is it not a guidance for them, how many generations We have destroyed before them in whose dwellings they do walk about? Verily, therein indeed are signs. Would they not then listen? 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 And they say: When will this Decision arrive if ye are truthtellers? 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
