Mazahir is the name of one of Prophet Muhammad's Sahabah (peace be upon them all). This name is defined as "appearances," by one source. On a side note, it is a name generally given to a person who is totally cool, incredibly sweet, and completely adorable.
Person 1: Oh, you're so sweet and adorable and cool! You're name must be Mazahir.
Person 2: Thanks. It is. How did you know?
Person 1: Because if you're name is Mazahir that means that you're totally cool, incredibly sweet, and completely adorable.
Person 2: Oh okay...if you say so.:)
