It is astonishing how soon the Arabs fade out of Muslim history, Arabia itself excepted. There are notable instances to the contrary like the Hamdanids and the Banū Hilāl, but they are few. During the rule of the Fatimids in Egypt the Banū Jarrah of Tai' were the most important of the bedouins in Syria; their chief Mufarrij b. Daghfal b. Jarrāh died in 404/1013 and his son Hassān succeeded him. Contemporary with Hassān was Fadl b. Rabi'a b. Hāzin b. Jarrāh, who was, perhaps, as Ibn Khaldūn suggested and Ibn Hajar affirmed, the ancestor of the Āl Fadl: This Fadl was at times an ally of the Franks and at times an ally of thesultan of Egypt. He was banished and joined Sadaqa b. Mazyad and in 500/1106 was the ally of Sadaqa against the Saljūq sultan Muhammad b. Malikshāh; later he abandoned Sadaqa.
