Assuredly We vouchsafed the Book unto Musa; so be thou not in doubt in thy receiving it. And We appointed it to be a guidance unto the Children of Is'rail. 23 And We made from among them leaders guiding by Our command when they were patient and [when] they were certain of Our signs. 24 On the Day of Resurrection your Lord will distinguish between them that on which they varied. 25 Did (these historical events) not make them realise that We destroyed many nations before them amidst whose dwellings they now move about? Surely there are many Signs in this. Are they unable to hear? 26 Have they not seen that We drive the water to the barren land and cause crops to grow which they and their cattle consume? Why, then, they will not see? 27 They say, "If what you say is true, when will the final triumph come?" 28 Say, "On the day of the final triumph, the faith of the disbelievers will be of no avail to them, nor will they be given any respite". 29 Therefore turn away from them and wait – indeed they too have to wait. 30
