In his efforts to spread Islam he established liberties for the Mawali by abolishing the jizya tax for converts to Islam. Imam Abu Muhammad Adbullah ibn Abdul Hakam stated that Umar ibn Abd al-Aziz also stopped the personal allowance offered to his relatives stating that he could only give them an allowance if he gave an allowance to everyone else in the empire. Umar ibn Abd al-Aziz was later poisoned in the year 720. When successive governments tried to reverse Umar ibn Abd al-Aziz's tax policies it created rebellion.
