Banu Khazraj

The Banu al-Khazraj (Arabic: بنو الخزرج‎‎  Arabic pronunciation: [ˈbanuː al.ˈxazrad͡ʒ]) was one of the tribes of Arabia during Prophet Muhammad's era. The Banu al-Khazraj are renowned for their generosity and hospitality.

Aws and Khazraj were known as Banū Qayla (بنو قيلة  [ˈbanuː ˈqajla]) in pre-Islamic era.

Abu Muhammad Al-hasan Ibn Ahmad Al-hamdani mentioned that The Banu Khazraj along with Banu Aws settled the area of Yathrib around the 2nd century ad as part of the PreIslamic Exodus of Yemen due to the Great Dam damage.

However, all sources agree that the Banu Khazraj and Banu Aus became hostile to each other.

Jewish chronicles state that they went to war against each other in the Battle of Bu'ath a few years before the Islamic prophet Muhammad migrated to Medina.

There were three Jewish tribes present in Medina: Banu Qaynuqa, Banu Nadir and Banu Qurayza.

During the battle, The Banu Nadir and the Banu Qurayza fought on the side of the Banu Aus, while the Banu Qaynuqa were allied with the Banu Khazraj. The latter were defeated after a long and desperate battle.

The Nusaybah clan family of Jerusalem, Custodians of the Church of the Holy Sepulchre, are descendants of Banu Khazraj. They arrived in Jerusalem with the 7th century Islamic conquest.

The Banu Aus were included in point 30-31 of the Constitution of Medina as allies to the Muslims, being as "one nation/community with the Believers".
