Banu Thaqif
The tribe formed part of the larger Qays Aylan group (also known simply as "Qays"). In the traditional sources, references to the Hawazin were often restricted to certain descendants of the tribe, known as "ʿUjz Hawāzin" (the rear of Hawazin); these subtribes were the Banu Sa'd, Banu Nasr and Banu Jusham. The founders of these subtribes were either the sons of Bakr ibn Hawazin or the sons of Mu'awiya ibn Bakr ibn Hawazin. Two other major branches of the Hawazin, the Banu 'Amir ibn Sa'sa' and the Banu Thaqif, were often grouped separately from the other Hawazin sub-tribes.
