The Book of Beliefs and Opinions (Judeo-Arabic: כתאב אלאמאנאת ואלאעתקאדאת; Arabic: كتاب الأمانات والاعتقادات, romanized: Kitāb al-Amānāt wa l-Iʿtiqādāt) is a book written by Saadia Gaon (completed 933) which is the first systematic presentation and philosophic foundation of the dogmas of Judaism.
The work was originally in Judeo-Arabic in Hebrew alphabet with quotations from the Torah. The first Hebrew translation was done in 1186 by Judah ben Saul ibn Tibbon, titled Emunot ve-Deot (Hebrew: אמונות ודעות Beliefs and Opinions). An unabridged translation into English by Samuel Rosenblatt was published in 1948.
