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 and [as] We raised among them leaders who, so long as they bore themselves with patience and had sure faith in Our messages, guided [their people] in accordance with Our behest [so, too, shall it be with the divine writ revealed unto thee, O Muhammad.] 24 On the Day of Resurrection your Lord will distinguish between them that on which they varied. 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 Have they not seen how We drive the water to the dry land and bring forth crops therewith whereof their cattle and themselves eat? What, will they not see? 27 But they answer: "When will that final decision take place, if what you [believers] say is true?" 28 Say: On the day of judgment the faith of those who (now) disbelieve will not profit them, nor will they be respited. 29 So withdraw from them (O Muhammad), and await (the event). Lo! they (also) are awaiting (it). 30
