Sharon, Corpus Inscriptionum Arabicarum Palaestinae, 2004. Brill. Leiden/Boston. p. 242 "A small village built on a steep hilltop, 500m. above sea level, in the heart of Samaria, Southwest of the small town of Salfit. Samaritans populated it until the Arab conquest, and probably throughout the Umayyad period. Under the Crusaders its name is not mentioned, but its location suggests that it was included in the Royal Domain of the Latin Kingdom of Jerusalem. (Riley-Smith, Atlas, 1991: 36-37) In 1187, after the battle of Hittin, it came under Ayyubid rule. In Islamic literature its name appears connected with the name of a Muslim scholar, Abdallah b. Abu Abdallah al-Farkhawi (d. 818/1415). In his biography, as-Sakhawi remarked that the nisbah al-Farkhawi refers to the village of Farkha, which he spells with a long “a” (also Guerin, Samarie, 2, 1875:159) adding that it was a village in the district of Nabulus. (Sakhawi, I)aw\ 5:29) Except for this remark I found no other mention of the village in the literary sources. This fact grants the present Ayyubid inscription, found in the village and mentioning its name, particular significance."
The full text of the inscription is: "Basmalah. They only shall manage (visit, perform the umrah to) Allah’s places of worship who have believed in Allah and the Last Day. (Q, 9:18; trans. Bell) This blessed mosque was renewed particularly by the funds of the inhabitants of the village known (by the name of) Farkhah that belongs to the sub district of the divinely protected town of Nābulus, as a pious deed for the sake of Allah—the exalted—and seeking His approval. Those who assumed charge of the work were Mansūr b. Abū al-Fawāris and Kāmil b. Sinān (or Sayyār) and Nāsir b. Muhammad who are all in need for Allah’s compassion. And the most exalted the great Amīr Bahā' ad-Dīn Alūdākh(?) b. 'Abd Allah has endowed for it from the (income of the) fasal of the aforementioned village every year three Tyrian dinars seeking the approval of Allah and (hoping to) gain the abode of the world to come. And this took place on the full moon of the month of Shawwāl the year 606 (=12.4.1210) and may Allah bless Muhammad." Sharon, 2004, pp. 188 -200
