The ruling on the phrase "O Lord of lords"

Question:
May Allah reward you. A noble questioner asks: What is the ruling on this phrase, "O Lord of lords"?

Answer:
Yes. The term "Lord" (al-Rabb) is used, and it refers to Allah (Glorified and Exalted is He), encompassing the general lordship over all created things. The term "Lord" is also used for the owner of a thing, such as the lord of the house or the lord of the family. However, when used for other than Allah, it must be qualified, so one says "lord of the house" or "lord of the family." As for using the term "Lord" without qualification, this is reserved exclusively for Allah (Glorified and Exalted is He). Therefore, one does not call a created being "Lord"; rather, one says "lord of a shoe," for example. This is like the statement of 'Abd al-Muttalib, "I am the lord of this camel," and the statement, "The House has a Lord who protects it." The meaning of "Lord of lords" is "Lord of owners." Allah (Mighty and Majestic) is the Owner of dominion and the Owner of all created things, and He is the Lord of lords, meaning the Lord of owners. Yes.
