Indeed, We gave Moses the Book; so he not in doubt concerning the encounter with him; and We appointed it for a guidance to the Children of Israel. 23 And We appointed, from amongst them, leaders guiding others by Our command, when they had persevered, and of Our signs they were convinced. 24 Verily thy Lord! He shall decide between them on the Day of Judgment concerning that wherein they have been differing. 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 that We drive the water [in clouds] to barren land and bring forth thereby crops from which their livestock eat and [they] themselves? Then do they not see? 27 They say: "When will this decision be, if ye 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 Therefore turn away from them and wait as they are waiting. 30
