Harb
The Harb were an Arab tribal people of the Hejaz around Medina. Genealogists traced them to the Khawlan of southern Arabia; their lands extended from the Red Sea coast east into the Najd.
The historian Ibn Khaldun identified Banu Harb with the Zubayd of the Hejaz. In the fifteenth century al-Qalqashandi also described the Zubayd of the Hejaz. Later Harb branches settled in Iraq and the Gulf, while the Banu Salim and Masruh comprised many clans.
