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 We appointed some of the Israelites as leaders for their exercising patience to guide the others to Our commands. They had firm belief in Our revelations. 24 Verily thy Lord will judge between them on the Day of Judgment, in the matters wherein they differ (among themselves) 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 Do they not see that We drive the rain towards a land that is dry, then grow grain from it which their cattle and they themselves eat? Will they not see even then? 27 And they say, "When will be this conquest, if you should be truthful?" 28 Say: "On the Day of Decision, no profit will it be to Unbelievers if they (then) believe! nor will they be granted a respite." 29 So turn thou away from them, and wait; they too are waiting. 30
