Later posts: Abu Nasr Fath al-Qal'i, also known by his laqab (honorific epithet) of Mubarak al-Dawla wa-Sa'id-ha ("Blessed and Happiness of the State"), was the governor of the Citadel of Aleppo during the reign of Emir Mansur ibn Lu'lu' (r. 1008–1016).
As governor of Jerusalem, Fath helped the Fatimid general Anushtakin al-Dizbari suppress a rebellion by the Jarrahids in 1024–1025 and maintained order between the Rabbinate and Karaite Jewish sects during the Hoshana Rabbah festivals at the Mount of Olives in 1029 and 1030.
[2] Salih soon after became a major opponent of Mansur, capturing him the same year of his prison escape then releasing him in return for half of Aleppo's revenues.
[7] Indeed, Fath was inclined to accept Salih's arrangement, but he faced protests from the people of Aleppo, who rejected the Bedouin rule of the Kilab.
[9] In 1024, the Jarrahid chieftain of the Tayy, Hassan ibn Mufarrij, assaulted Jerusalem during his rebellion against Anushtakin al-Dizbari, the Fatimid governor of Palestine.
[12] However, the move was voided by the intervention of the Jewish geonim leaders and local Fatimid governors,[12] including Fath and al-Dizbari.
[13] The following year, al-Dizbari issued an edict warning the Rabbinates not to ban the Karaites and had Fath and his troops supervise the festival with lashes and chains prepared to deter such actions.
