مضر

Mudar (Arabic: مُضَر) was one of the principal tribal confederations of northern and central Arabia in late antiquity and the early Islamic period. Mudar rose to power over the Hejaz in the fifth century, after supplanting its predecessor, the Banu Ghassan, who migrated to Syria. The chief tribes over Mudar may have been the Salihids early on, and then Banu Tha'labah, and finally in the early sixth century, Banu Ghassan.
