Have they not reflected upon their own being? Allah only created the heavens and the earth and everything in between for a purpose and an appointed term. Yet most people are truly in denial of the meeting with their Lord!

Do they not think deeply (in their ownselves) about themselves (how Allâh created them from nothing, and similarly He will resurrect them)? Allâh has created not the heavens and the earth, and all that is between them, except with truth and for an appointed term. And indeed many of mankind deny the Meeting with their Lord. [Tafsir At-Tabarî].
