[Who is] possessed of power and with the Owner of the Throne, secure [in position]

The noble messenger is further described as ‎ذِى قُوَّةٍ‎, possessor of great might and power. Why is power important for a messenger?

Because this is classified, crucial information that someone might try to intercept or corrupt. When high-security documents are transported in this world, armed guards surround them.

But Gabriel (peace be upon him) needs no guards; he himself possesses overwhelming power. No one can overpower him and steal or alter the message he carries.

Then Allah describes him as ‎عِندَ ذِى ٱلۡعَرۡشِ مَكِينٍ‎: stationed in the company of the Owner of the Throne, firmly established there. This addresses proximity and access.

When delivering a highly sensitive message, you cannot have multiple links in the chain where the message could be compromised. The messenger must have direct access to the highest authority.

Gabriel (peace be upon him) is right there by the Throne itself; there is no intermediary between him and Allah. He receives the revelation directly from the highest source.

The word ‎مَكِين‎ is profound. It comes from ‎تَمۡكِين‎ and ‎مَكَانَة‎, indicating someone of extremely high status, someone permanently established and secure in their position.

Someone whose rank is recognized and respected by all, someone who has been there and whose authority cannot be challenged.

This is the station of Gabriel (peace be upon him): firmly established in the highest realm, trusted completely.
