Banu Qurayza
The Banu Qurayza (, ; alternate spellings include Quraiza, Qurayzah, Quraytha, and the archaic Koreiza) were a Jewish tribe which lived in northern Arabia, at the oasis of Yathrib (now known as Medina), until the 7th century, when the men were sentenced to death and women and children enslaved after they betrayed the pact made with the Muslims following the Invasion of Banu Qurayza by Muslim forces under Muhammad.
