COMMENTARY on 40:16
Mustafa Khattab:

Translation:
the Day all will appear ˹before Allah˺. Nothing about them will be hidden from Him. ˹He will ask,˺ “Who does all authority belong to this Day? To Allah—the One, the Supreme!2
Commentary:
2   It is reported in a ḥadîth collected by Imâm Muslim that everyone and everything that has ever existed will die on that Day, except for Allah—the Eternal. He will then ask, “Who does all authority belong to this Day? Where are the kings of the world? I am the King.” Since no one will be there to answer, Allah will answer Himself, “˹All authority belongs˺ to Allah—the One, the Supreme!”

 

A. Yusuf Ali:

Translation:
The Day whereon they will (all) come forth: not a single thing concerning them is hidden from Allah. Whose will be the dominion that Day?" 4379 That of Allah, the One the Irresistible!
Commentary:

4379  The Kingdom of Allah—of Justice, Truth, and Righteousness-will then be fully established. Evil can then no more come into competition with Good, even in the subjective consciousness of man.
