مَالِكُ الْمُلْكِ
MALIKUL-MULK
(The Eternal Possessor of Sovereignty)
The One who controls the Dominion and gives dominion to whoever He willed.
Allah is Malikul-Mulk, The Lord of the Kingdom. He is the sole owner of all creation and with absolute authority can act in any manner, any time, and in anyway.
From the root m-l-k which has the following 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.
Say, "O Allah, Owner of Sovereignty, You give sovereignty to whom You will and You take sovereignty away from whom You will. You honor whom You will and You humble whom You will. In Your hand is [all] good. Indeed, You are over all things competent. (Quran 3:26)
