[2] Under al-Muntasir's successor al-Musta'in (r. 862–866), he led a Turkish army to quell a tribal uprising in Jordan after the local authorities proved incapable of defeating it themselves.
Muzahim defeated the rebels and forced the 'Alid to flee; he also ordered his troops to set fire to al-Kufah after encountering resistance within the city.
After putting down an uprising in the Hawf of Lower Egypt, Muzahim and his chief of security (shurtah) Azjur al-Turki shifted their focus to defeating Jabir.
The next several months were spent on campaign against the rebel, and the latter finally sued for peace in August 867; Muzahim, however, imprisoned him in al-Fustat, and in the following year Jabir was sent to Iraq.
[9] According to the Egyptian historian al-Kindi, during Muzahim's administration his lieutenant Azjur mandated a number of ritual practices that were previously foreign to Egypt.
