Ali ibn Sahl Rabban al-Tabari, the son of a Syriac Christian scholar living in Persia on the Caspian Sea...
Sahl b. Bishr (d. 822 or 850), known in Latin as Zael or Zahel
Ibn al-Qiftî (4) renders the title Rabban correctly but with a false explanation, taking it for the Jewish title of Rabbi. So 'Alî b. Rabban passed into all historical works, until quite recently, as a Muslim of Jewish origin, although 'Alî himself, in the preface to his work, explains this title Rabban as being the Syriac word for "our Master" or "our Teacher". The late Professor Horovitz told me and wrote to me several years ago, that this was a Christian title; A. Mingana gave the proof of this in print for the first time in I922. 'Alî says in his apologetic tract "The Book of Religion and Empire", which he wrote about 855 A.D., that he himself was a Christian before he was converted to Islam, and that his uncle Zakkâr was a prominent Christian scholar.
