Banu Khazraj
There were many Jewish tribes in Medina: Banu Nadir, Banu Qurayza, Banu Qaynuqa and so many others. During the battle, the Banu Nadir and the Banu Qurayza fought with the Banu Aus, and the Banu Qaynuqa were allied with the Banu Khazraj. The latter were defeated after a long and desperate battle.
