Mustafa Nayyem, who is Pashtun (
https://en.wikipedia.org/wiki/Mustafa_Nayyem), has a brother, whose name is Masi. I've found some evidence about similarly sounding Persian names Maseeh/Maseh, which seem to be Arabic forms of
Messiah.
BTW, article on Masih Alinejad (
https://en.wikipedia.org/wiki/Masih_Alinejad) says that her name (actually it's a pseudonym) also means "
Messiah". Is there actually a clear link between all these name forms?
(I have no connection to Persian or Afghan culture and look forward to getting answer from anyone who is competent in this field).
