Abdullah bar Sam was born into the Manduia and ‛Kuma families in Qal'at Saleh, Iraq, probably sometime just before the turn of the 20th century. His father's name was the Ganzibra Sam, son of Sheikh Jabbar. Abdullah bar Sam's Mandaean baptismal name was Adam Zihrun bar Sam (Classical Mandaic: ࡀࡃࡀࡌ ࡆࡉࡄࡓࡅࡍ ࡁࡓ ࡎࡀࡌ, romanized: Adam Zihrun br Sam).[1]
Ganzibra Abdullah copied the Ginza Rabba by hand in 1928; as of 2010, that copy of the Ginza Rabba belonged to the Elmanahi family in New York state, United States.[1]: 65–66
