Salman the Persian
Salman Farsi (born Ruzbeh Khoshnudan; Persian: سلمان فارسی; Arabic: سَلْمَان ٱلْفَارِسِيّ) was a Persian religious scholar and one of the companions of Muhammad. As a practicing Zoroastrian, he dedicated much of his early life to studying to become a magus, after which he began travelling extensively throughout West Asia to engage in constructive dialogue with non-Zoroastrian groups.
