The eternal owner of sovereignity.
“Say: “O ALLAH! LORD OF POWER (AND
RULE), Thou givest Power to whom Thou pleasest, and Thou strippest off Power from whom Thou pleasest: Thou enduest with honour whom Thou pleasest, and Thou bringest low whom Thou pleasest: in Thy hand is all Good. Verily, over all things Thou hast power.”
(3:26) The Holy Quran
From the root m-l-k with the classical Arabic connotations: to possess, to own exclusively to exercise authority to command to have power over, command, reign to have dominion over, to have ruling power to have kingship
