Brief accounts of Abraham's patriarchate are given in the Ecclesiastical Chronicle of the Jacobite writer Bar Hebraeus (floruit 1280) and in the ecclesiastical histories of the Nestorian writers Mari (twelfth-century), ʿAmr (fourteenth-century) and Sliba (fourteenth-century).
The following account of Abraham's patriarchate is given by Bar Hebraeus:
Sabrishoʿ II was succeeded by Abraham II, from the monastery of Beth ʿAbe, who was a man pure and chaste in body but not learned, and not up to the task of governing the church. His nephew Ephrem, his sister's son, and another son by a concubine used their power perversely. During his time the Christians were in sore straits, as the Arabs demolished several churches in Basra.
