بنو خزرج
Medina, Hejaz, Western Arabia · Polytheism (pre-Islamic); Islam (post-conversion)
The Banu Khazraj is a large Arab tribe originally from South Arabia, who migrated to Yathrib (later Medina) following the destruction of the Marib Dam. They played a significant role in early Islamic history as one of the Ansar tribes that supported Prophet Muhammad after his migration to Medina. Notable members include Sa'd ibn Ubadah and Anas ibn Malik. The tribe was historically hostile to their cousins, the Banu Aws, but both became key supporters of Islam.
