Isaac was succeeded by Simon the Syrian, whom the Koptic church looks upon as a saint, and for whom is claimed the power of reviving the dead. He nevertheless died from the effects of poison given him at the altar by some jealous rival. Arab historians relate how deputies came to Simon from India to ask for a bishop and some priests. The patriarch refused to comply with this request, but Abd el-Aziz, thinking that this relation with India might prove politically useful, gave the order to other and more docile priests.
The patriarchal seat was empty for three years after the death of Simon. The Kopts next appointed a patriarch named Alexander, who held the office for a little over twenty years. The Koptic writers who recount the history of this patriarch mention their discontent with the governor Abd el-Aziz. The monks and other members of the clergy had grown very numerous in Egypt and claimed to be exempt from taxation. Abd el-Aziz, whose yearly tax was fixed, thought it unjust that the poorest classes of the people should be made to pay while the priests, the bishop, and the patriarch, all possessing abundance, should be privileged by exemption. He therefore had a census made of all the monks and put on them a tax of one dinar (about $2.53), while he exacted from the patriarch an annual payment of three thousand dinars, or about $7,600. This act of justice was the cause of many complaints among the clergy, but they were soon suppressed and were without result.
After more than twenty years of a prosperous government of Egypt, Abd el-Aziz ibn Merwan died at Fostât in the year 708 (a.h. 86) at the very time when, with many fresh plans for the future, he had completed the building of a large and magnificent palace called ed-Dar el-mudahaba (the golden house), and a quarter of the town called Suk el-hammam (the pigeon market). The Caliph Abd el-Malik felt deeply the loss of this brother, whose qualities he highly appreciated and whom he had appointed as his successor.
He now named as his heir to the caliphate Walid, his eldest son, and replaced Abd el-Aziz in the government of Egypt with his second son, Abd Allah ibn Abd el-Malik. The Kopts hoped to obtain from the new governor the repeal of the act that exacted yearly tribute from the clergy, but Abd Allah did not think it fair to grant this unjust discrimination against the poorer classes of the Egyptians. Those monks who have written the history of the patriarchs have therefore painted Abd Allah in even blacker colours than they did his predecessor. For the rest, Abd Allah only held the reins of government in Egypt until the death of his father, which occurred a few months later.
Suleiman succeeded his brother Walid I. The new caliph vigorously put into execution all the plans his brother had formed for the propagation of the religion of the Prophet. In the first year of his reign he conquered Tabaristan and Georgia, and sent his brother Maslama to lay fresh siege to Constantinople. On his accession to the throne Suleiman placed the government of Egypt in the hands of Assama ibn Yazid, with the title of agent-general of finances.
