Arab people
In Islamic and Jewish tradition, Arabs are a Semitic people from the Ishmaelites, who trace their ancestry from Ishmael, a son of the ancient patriarch Abraham and Hagar and of the sons from Abhraham and his wife Keturah. Medieval Arab genealogists separate the Arabs into two groups: the "original Arabs" (Bedouin) of South Arabia, descending from Qahtan (identified with the biblical Joktan) and the "Arabized Arabs" (musta`ribah) of North Arabia (The Levant), descending from Adnan who is descended from Ishmael.
