Meaning of Allah's Name Maalik and Malik according to Quran and Sunnah
Al-Malik (the Sovereign), al-Maalik (the Possessor), Alladhi lahu’l-Mulk (the One to Whom Dominion belongs). Allaah is the One Who is described with the attributes of sovereignty and dominion, which are the qualities of might and pride, subjugation and control. He is the One Who is in absolute control of creation, Who issues commands and Who rewards or punishes. The entire Universe, high and low, belongs to Him. All of them are His servants and slaves, and are utterly dependent on Him.
