                    In hagiography: The
                        patriarch Isaac became bishop of Ḥarran by the protection
                        of the governor of the al-Jazira, ʿAbd
                            Allāh. Issac became Patriarch when ʿAbd Allāh became
                            Caliph Al-Mansur. But Al-Mansur had Patriarch Isaac
                        killed and his body thrown into the Euphrates.
