Beginnings The Jarrahids (Banu al-Jarrah) were the ruling clan of the
Tayy tribe. The Jarrahids initially controlled fortresses in the
Sharat mountains. The first member of the Banu al-Jarrah to be mentioned in the historical record was Daghfal ibn al-Jarrah, an ally of the
Qarmatians. He was based in
al-Ramla, the center of
Jund Filastin (District of Palestine).
Reign of Muffarij and its surroundings in 1895. The Jarrahids under
Mufarrij ibn Daghfal and his son
Hassan intermittently governed, controlled or plundered Ramla in the late 10th and early 11th centuries Daghfal's son,
Mufarrij, entered the historical record during the Fatimid struggle with
Alptakin, a Qarmatian-backed
Buyid commander who took over Damascus. In return for the Jarrahids' support, al-Aziz made Mufarrij
wālī (governor) of Ramla. Abu Taghlib and his Uqaylid allies attacked Ramla in August, but were defeated and captured on 29 August by the Jarrahids, who by then regained Fadl's support. The latter requested Mufarrij hand over Abu Taghlib to Caliph al-Aziz, but fearing Abu Taghlib could be potentially used by the Fatimids against him, Mufarrij killed him and sent his head to the caliph instead. At that point, the Jarrahids controlled the entire interior of Palestine from the boundary with Egypt up to Tiberias. Ali and Mahmud surrendered to the advancing Fatimid army, while al-Hakim had Mufarrij poisoned to death. Hassan, as a representative of the Tayy, entered his tribe into an alliance with the
Kalb under Sinan ibn Sulayman and the
Kilab under
Salih ibn Mirdas. Instead, Anushtakin took the initiative to extract taxes from Hassan's
iqtaʿ at
Bayt Jibrin and deprive him of the revenues, which ended with the killing of Anushtakin's soldiers. This escalated the conflict with the Jarrahids, particularly after Anushtakin imprisoned two of Hassan's chief aides in
Ascalon. The Jarrahids and the Byzantines struck an alliance in 1030. Afterward, Hassan and his son
Allaf are mentioned on occasion, such as their assistance in the Byzantine defense of
Edessa from the
Marwanids and
Numayrids in 1035/36. As a result, Hassan was forced into confinement in Constantinople until 1040 as a means to prevent his tribe, with its unstable allegiances, from potentially attacking Antioch. According to Syrian historian Mustafa A. Hiyari, information on Rabi'a in the medieval sources is confused, though he most likely was an emir of Bedouin auxiliaries for the
Burid ruler of Damascus,
Toghtekin (r. 1103–1128). This prompted Toghtekin to expel Fadl from Syria, after which he formed an alliance with
Sadaqa ibn Mansur, the chieftain of the Arab
Mazyadid dynasty in Iraq, before defecting to the
Seljuks. ==Descendants==
