بكر بن وائل
According to Ya'qubi, in his 9th-century book Kitab Futuh Al-buldan, after the Umayyad expansion into north Mesopotamia (661–750), there was a resettlement by the Umayyad caliph Muawiyah I of the Arab tribe of Banu Bakr from Najd in central Saudi Arabia to the region of Mardin, possibly being the ancestors of the Mhallami.
