Verily We bestowed the Book upon Moses. So entertain no doubt if (the Prophet Muhammad) received the same. We had made that Book a guidance for the Children of Israel, 23 and when they remained steadfast and firmly believed in Our Signs, We created among them leaders who guided people by Our command. 24 Verily, 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 also ask: 'When will this Opening come, if what you say is true' 28 Say: 'On the Day of Opening the faith of the unbelievers will not benefit them, nor shall they be respited' 29 So withdraw from them (O Muhammad), and await (the event). Lo! they (also) are awaiting (it). 30
