Sidi ibn Ibrahim al-Taras
Sidi ibn Ibrahim ibn Hasdai al-Tarās was a 11th century Sephardic Karaite scholar.
Born in Castile, Spain around 1065. According to Abraham ibn Daud, al-Taras went in his youth from Castile to Eretz Israel, where he became a pupil of the Karaite scholar Jeshua ben Judah. He returned Spain, settling in Andalusia, where he tried to gain adherents for Karaism among the Rabbanites. After his death, his wife, who is referred to by the Karaites as "al-Muʿallima" was considered by them an authority on religious practice. She continued to spread the tenets of Karaism, leading to Joseph Ha-Nasi Ferrizuel convincing Alfonso VI to expel the Karaites from all the Castilian towns except one.
