What is the meaning of my names "Sadeen" and "Sulaf" in the Arabic language, and is it permissible to name with them Islamically?

The word "Sadeen" is mentioned in Arabic dictionaries with the meanings of fat/grease, covering, and letting down a garment or curtain. No one named "Sadeen" has been found in linguistic or biographical books. There is no শরীʿআ (Sharia) prohibition against being named "Sadeen," although a familiar name with a good meaning is preferable.
