Letter from Elijah (probably in Salonika) to his brother, a scholar (probably in Fusṭāṭ), written in the 11th-century. The letter mentions Elijah’s compatriot, Abū ʿAlī, who had visited Fusṭāṭ and brought back letters from Elijah's brother, and letters for a community leader, Elijah b. Shabbetay, dealing with the case of a Jewish man in prison. Elijah’s brother had sent him a gift of a scroll of Esther on vellum, and in return Elijah sent his brother a collection of piyyuṭim. Elijah describes friction between the Karaites and Rabbanites in Byzantium and requests his brother’s help in championing the Karaite cause. (Information from CUDL)
