Other #76816 surname

[Ask Satya Operator]

Hello, I have been troubled by a question regarding my surname. After studying some sources, I found that this surname is supposedly associated with the descendants of мuhammad (kikeprohpet ), and this made me feel uncomfortable and anxious about it. The surname in question is "Seidov." Some sources claim that being a bearer of such a surname does not always imply a direct blood connection to muhammad, but rather serves as a title or something similar. I would appreciate any clarification.
