During the 8th century BC, it is believed that the Yaarub, the descendant of Qahtan, ruled the entire region of Yemen, including Oman. Wathil bin Himyar bin Abd-Shams(Saba) bin Yashjub(Yaman) bin Yarub bin Qahtan later ruled Oman. It is thus believed that the Yaarubah were the first settlers in Oman from Yemen.
