What is the meaning of the name "Fayy", and is it permissible to name someone with it Islamically?

The name "Fi" has not been found in available sources, so its meaning or ruling cannot be determined, unless its origin is "Fay'" (shade) and the hamza was softened. The first letter cannot be a shaddah (doubled consonant) in Arabic. One should avoid naming children with strange and unknown names in Muslim society, as negative consequences may result. There are Islamic guidelines for naming children, which must be adhered to in order to avoid violating the Sharia.
