	According to the 10th-century Melkite Christian patriarch Eutychius of Alexandria, Abd al-Aziz permitted his Melkite servants to establish a small church in Hulwan dedicated to Saint George. One of the governor's Jacobite secretaries, Athanasios, was also allowed the construction of a church in close proximity to the Babylon Fortress (Qasr al-Sham) in the vicinity of Fustat.
