The Meaning of Ar-Rabb, the Lord
Ar-Rabb is the owner who has full authority over his property. Ar-Rabb,
linguistically means, the master or the one who has the authority to lead. All
of these meanings are correct for Allah. When it is alone, the word Rabb is used
only for Allah. As for other than Allah, it can be used to say Rabb Ad-Dar, the
master of such and such object. Further, it was reported that Ar-Rabb is Allah's
Greatest Name.
