[2] According to vladimir Minorsky, The name of the Tribe is derived from geographical term for the region of Irbil, which is preserved in the name of the Nestorian diocese, Adiabene (HaSayyap).

Their dominion included the regions of Maragha and Urmia to the east, Arbil, Sinjar, and parts of Jazira to the south and west, and Barkari, Hakkari and Salmas to the north,[1][7] as Erbil being one of their capital,[8] ruling from 906 to 1131/1144.

The Abbasid caliph of Baghdad sent reinforcement and Abu'l-Hayja continued his perusing Muhammad ibn Bilal along with 5,000 Hadhbani Kurdish families.

A peace was made and the Muhammad ibn Bilal had to surrender all their territories in northern Mosul to Daseni and Humaydi Tribe.

The Abbasid caliph al-Qa'im (r. 1031–1075) convinced the Rawadids and the Hadhabanis to band together and recapture Barkari; they briefly reoccupied it until losing it permanently to the Byzantines.
