Rabīʿa ibn Nizar is a principal branch of the Adnanite North Arabian tribes, alongside Mudhar. Originating from the Tihamah region of western Arabia, Rabīʿa migrated northwards and eastwards, establishing various sub-tribes across Eastern Arabia, Mesopotamia, and southern Arabia. Several sub-tribes, such as Abd al-Qays and Taghlib, were predominantly Christian before Islam, while others worshipped idols. Notable descendants include influential poets, warriors, and scholars, and royal families such as the Al Saud and Al Khalifa trace their lineage to Rabīʿa.
