Eastern Arabia · Christianity (pre-Islamic); Islam (post-conversion)
The ʿAbd al-Qays is an ancient Arabian tribe originating from the Rabi'a branch of the North Arabian tribes, primarily located in Eastern Arabia. Historically, they were known for raiding Iran in pre-Islamic times and later migrated to the oases of al-Ahsa, Tarout Island, and Qatif. During the early Islamic period, members of the tribe participated in the Arab conquest of Iran and settled in regions such as Fars and Basra. The majority of the Baharna people today descend from the ʿAbd al-Qays tribe.
