Mir Jafar bin Mir Hasan Dasni (Kurdish: Mîr Ceferê Dasnî), also known as Jafar bin Faharjis, was a ezidi leader who in 838 launched an uprising against Abbasid Caliph al-Mutasim in the area north of Mosul.
Due to the difficulty of the terrain, the Arab army proved unsuccessful, suffered heavy casualties and a number of its commanders including Abdullah's uncle Ishaq bin Ans and his father-in-law were killed.
Al-Mu'tasim had purchased a Khazar slave, called Itakh.
Itakh defeated Mir Jafar's troops in 841 and killed many Kurds.
[3] In order to avoid being captured alive, Mir Jafar committed suicide by drinking poison.
