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 how We drive water (rain clouds) to the dry land without any vegetation, and therewith bring forth crops providing food for their cattle and themselves? Will they not then see? 27 And they say: When will this Decision arrive if ye are truthtellers? 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 So turn away from them and wait. Indeed, they are waiting. 30
