Saʽadia’s major work, The Book of Beliefs and Opinions, was translated into English by Samuel Rosenblatt, who said in its introduction: “Even though... he was the authority in his day on the Talmud, [Saʽadia] makes comparatively sparing use of this source of Jewish tradition, apparently because it was his desire to defeat with their own weapons the Karaites who accepted only the Written Law as binding. ”
Saadia peateose „Tõekspidamiste ja arvamuste raamatu ” tõlkis inglise keelde pealkirjaga The Book of Beliefs and Opinions Samuel Rosenblatt, kes ütles oma sissejuhatuses:„ Kuigi.. [ Saadia] oli oma aja vaieldamatu autoriteet Talmudi alal, kasutab ta seda juudi pärimuste allikat võrdlemisi harva, sest ilmselt oli tema sooviks lüüa karaiime, kelle silmis oli kaalu ainult kirjalikul Seadusel, nende endi relvadega. ”
