Editing Saadia Gaon (section)

===Polemical writings===
# Refutations of Karaite authors, always designated by the name "Kitab al-Radd", or "Book of Refutation". These three works are known only from scanty references to them in other works; that the third was written after 933 is proved by one of the citations.
# "Kitab al-Tamyiz" (in Hebrew, "Sefer ha-Hakkarah"), or "Book of Distinction", composed in 926, and Saadia's most extensive polemical work. It was still cited in the twelfth century; and a number of passages from it are given in a Biblical commentary of [[Japheth ha-Levi]].
# There was perhaps a special polemic of Saadia against Ben Zuta, though the data regarding this controversy between is known only from the gaon's gloss on the Torah.
# A refutation directed against the rationalistic Biblical critic [[Hiwi al-Balkhi]], whose views were rejected by the Karaites themselves;
# "Kitab al-Shara'i{{'"}}, or "Book of the Commandments of Religion".
# "Kitab al-'Ibbur", or "Book of the Calendar", likewise apparently containing polemics against Karaite Jews;
# "Sefer ha-Mo'adim", or "Book of Festivals", the Hebrew polemic against Ben Meir which has been mentioned above.
# "Sefer ha-Galui", also composed in Hebrew and in the same flowery biblical style as the "Sefer ha-Mo'adim", being an autobiographical and apologetic work directed against the Exilarch (''rosh galuth''), David b. Zakkai, and his chief patron, Aharon ibn Sargado, in which he proved his own uprightness and equity in the matter of controversy between them.
