Al-Mu'tadid again departs for the district of Mosul in March 896 in order to campaign against Harun.

On this occasion he is joined by Hamdan ibn Hamdun's son al-Husayn, who had peaceably submitted to the caliph during the latter's struggle against his father.

Al-Mu'tadid himself advances to Takrit, while he dispatches al-Husayn and Wasif Mushgir to pursue Harun.

Al-Husayn meets the rebel near the Tigris and routs his forces; Harun attempts to flee, but al-Husayn pursues him and eventually catches up to him, together with one hundred of his followers.

Despite a plea by Harun to refrain from fighting, al-Husayn orders his men to attack; the Kharijites are again defeated and Harun himself is captured.
