Fort in Turubah, Saudi Arabia

In traditional Islamic history, the Qamūṣ () was one of the fortresses of the poet al-Rabi ibn Abu al-Huqayq and his tribe, who were Jews, the Banu Nadir. The fortress was situated near Khaybar in what is now Saudi Arabia. The fortress was attacked by Muslim forces and defeated circa 629/30 CE. It was after this event that Muhammad married Safiyya bint Huyayy. The Jewish presence in the region has been attested to the late seventh century who pioneered the cultivation in the area.
