al-Husayn ibn Ali ibn Isa, in which he was responsible for personally apprehending both al-Amin and his mother
Zubaydah bint Ja'far, and he was subsequently selected to lead the first pilgrimages undertaken in al-Ma'mun's name, in 812, 813 and 814.
In June 814 al-Abbas was appointed as governor of
Egypt by al-Ma'mun, and he deputized his son
Abdallah

jund'', however, and after less than three months in office he was overthrown by an army revolt, while the ex-governor
al-Muttalib ibn Abdallah al-Khuza'i was freed from prison and restored to power in his place. Al-Abbas then responded by setting out for Egypt in an effort to intervene, but in February 815 he suddenly died at
Bilbays, allegedly due to poisoning.
