Banu Khazraj

The Banu Khazraj (بنو خزرج) is a large Arab tribe based in Medina. They were also in Medina during Muhammad's era. The Banu Khazraj are a South Arabian tribe that were pressured out of South Arabia in the Karib'il Watar 7th century BC war versus Awsan and its allies (Aws - Awsan), (Qataban - Ghatafan), when the Sabaeans were eventually defeated by the Himyarites, the settled tribes became the pre-Islamic Azd tribe and were known as Banū Qayla (بنو قيلة ˈba.nuː ˈqaj.la) in the pre-Islamic era. Abu Muhammad Al-Hasan Ibn Ahmad Al-Hamdani mentioned that the Banu Khazraj and the Banu Aws settled the area of Yathrib around the 2nd century AD as part of the Pre-Islamic Exodus of Yemen because of the Great Marib Dam damage. However, all sources agree that the Banu Khazraj and Banu Aws 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 Aws, and the Banu Qaynuqa were allied with the Banu Khazraj. The latter were defeated after a long and desperate battle. The Nusaybah 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 Aws were included in point 30-31 of the Constitution of Medina as allies to the Muslims, being as "one nation/community with the Believers". Abd-Allah ibn Ubaiy, their chief, is said to have plotted against Muhammad. The Banu Khazraj and others became known as the Ansar. List of expeditions of Muhammad On 624 Muhammad ordered the assassination of Ka'b ibn al-Ashraf. According to Ibn Ishaq, Muhammad ordered his followers to kill Ka'b because he "had gone to Mecca after Badr and inveighed against Muhammad. He also composed verses in which he bewailed the victims of Quraysh who had been killed at Badr.
