Sheikh (Rabbi) Rishama Sattar Jabbar Hilo al-Zahrony is the patriarch and international head of the Mandaean religion in Iraq. He is currently based in Baghdad, Iraq, where he serves as the head of the Sabian–Mandaean Mandi of Baghdad.

Mandaeism, sometimes also known as Nasoraeanism or Sabianism, is a Gnostic, monotheistic and ethnic religion with Greek, Iranian, and Jewish influences. Its adherents, the Mandaeans, revere Adam, Abel, Seth, Enos, Noah, Shem, Aram, and especially John the Baptist. Mandaeans consider Adam, Seth, Noah, Shem and John the Baptist prophets, with Adam being the founder of the religion and John being the greatest and final prophet.
