Abu Sahl al-Farisi al-Nafusi

Abu Sahl al-Nafusi lived during the 3rd century AH (9th century CE), a time when the Ibadite Rustumid dynasty ruled in North Africa. He witnessed the changes that occurred following the dynasty's decline, which ultimately ended with the Shia Muslim Fatimid invasions. Despite the Arabic epithet al-Farisi meaning the Persian, which might suggest Persian origins, it is believed that Abu Sahl's mother may have been linked to the Rustumid family. This dynasty, some sources claim, had Persian roots, potentially connecting her lineage to his. However, historical records confirm that Abu Sahl was not Persian. Instead, he was a Nafusi Berber, as indicated by his second epithet, al-Nafusi, which signifies his Berber ancestry. Polish Orientalist Tadeusz Lewicki further supports the idea that Abu Sahl's father was a Nafusi Berber. Some sources also indicate that Abu Sahl's father was the son of Mimoun, who in turn was the son of Abd al-Wahhab, the son of Abd al-Rahman ibn Rustum, the first ruler of the Rustamid Imamate. Similarly, Tunisian historian Othman Kaak [fr] also notes that Abu Sahl may have been one of the grandsons of Abd al-Rahman ibn Rustum. Another version of the story suggests that both his father and mother were directly linked to the Rustumid family.

Historical Ibadi sources indicate that Abu Sahl, known for his fluency in Berber, served as a translator. He is believed to have worked for either the third Rustumid ruler, Aflah ibn Abd al-Wahhab (r. 824–872), or his grandson, Yusuf Abu Hatim ibn Muhammad (r. 894–897, 899–906), particularly in Berber. Contemporary Libyan scholar Ali Yahya Muammar believes that Abu Sahl translated for Yusuf Abu Hatim ibn Muhammad, not for his grandfather Aflah ibn Abd al-Wahhab. Muammar suggests that Abu Sahl was likely too young to serve Aflah. Algerian historian Ibrahim Bahaz proposes that Abu Sahl may have translated Arabic letters from the Rustumids into Berber for local governors in their provinces. After the fall of Tihert (in modern-day Algeria), the Rustumid dynasty's seat of power, to the Fatimid offensives, Abu Sahl is believed to have sought refuge along the Algerian coast. Historical sources suggest two possible locations for his resettlement: Marsa al-Kharraz and Marsa al-Dajaj. Ahmad al-Darjini (d. 1270 CE) argues that Abu Sahl settled in Marsa al-Dajaj rather than Marsa al-Kharraz. He reinforces his claim by stating:.mw-parser-output .templatequote{overflow:hidden;margin:1em 0;padding:0 32px}.mw-parser-output .templatequotecite{line-height:1.5em;text-align:left;margin-top:0}@media(min-width:500px){.mw-parser-output .templatequotecite{padding-left:1.6em}}

It is believed that Abu Sahl authored a diwan comprising 12 books in the Berber language, featuring poetic compositions that chronicle the history of the Ibadis (Ahl al-Daʿwa) in North Africa. His works take the form of elegies lamenting the fall of the Ibadi Rustumid Imamate, expressing profound sorrow for the faith, its followers, and their decline. According to Ahmad Al-Darjini, a figure named Said, from al-Nukkariyya, took 6 books from this collection without authorization. Upon discovering that Abu Sahl had dedicated his work to their community, the Ibadis sent a messenger to retrieve the collection from Said. The recovered portions, along with the remaining poems, were compiled into a single volume stored in Qal'at Darjin (in modern-day Tunisia). However, when the city was captured in 1040 (440 AH), all Ibadi manuscripts housed there, including Abu Sahl's collection, were burned and subsequently lost.
