Al Qamus Fort
Al-Qamus was the name of one of the fortresses of al-Rabi ibn Abu al-Huqayq, Banu Qurayza situated near Khaybar. The fortress was attacked by Muslim forces and it fell to Muslim forces in 629/30 CE.
It was after this event that Muhammad married Safiyyah bint Huyayy. Although traditionally it is believed to be the Qamus fort but there is no direct archaeological evidence. The Khaybar was still inhabited by Jews, as late as the late 7th century, who pioneered the cultivation of the oasis.
