Al-Jaathiya 45:24

And they say, “There is nothing but our life of this world: we die and we live[7], and nothing causes us to die except time.” They have no knowledge of that; they only speculate.

[7] i.e., some of us die without return, and others are born replacing them.

And they say, "There is not but our worldly life; we die and live,[1474] and nothing destroys us except time." And they have of that no knowledge; they are only assuming.

[1474] i.e., some people die and others live, replacing them.

24. And they say: "There is nothing but our life of this world, we die and we live and nothing destroys us except Ad-Dahr (time).[4] And they have no knowledge of it: they only conjecture.

[4] (V.45:24) Narrated Abu Hurairah رضي الله عنه: Allâh’s Messenger صلى الله عليه وسلم said: "Allâh said, ‘The son of Adam annoys Me for he abuses Ad-Dahr* (Time) though I am Ad-Dahr (Time); in My Hands are all things, and I cause the revolution of day and night.’ " (Sahih Al-Bukhari, Vol.6, Hadîth No.351).
* ‘I am Ad-Dahr’ means ‘I am the Creator of Time, and I manage the affairs of all creation including Time.’ One should not attribute anything whether cheerful or disastrous to Time, for everything is in the Hands of Allâh and only He is the Disposer of everything.

And they say: There is naught but our life of the world; we die and we live, and naught destroyeth us save time; when they have no knowledge whatsoever of (all) that; they do but guess.
