They know what is apparent of the worldly life, but they, of the Hereafter, are unaware. Do they not contemplate within themselves? Allah has not created the heavens and the earth and what is between them except in truth and for a specified term. And indeed, many of the people, in [the matter of] the meeting with their Lord, are disbelievers. Have they not traveled through the earth and observed how was the end of those before them? They were greater than them in power, and they plowed the earth and built it up more than they have built it up, and their messengers came to them with clear evidences. And Allah would not ever have wronged them, but they were wronging themselves.
