Sefer Hamitzvot ("Book of Commandments", Hebrew: ספר המצוות) is a work by the 12th-century rabbi, philosopher, and physician, Moses Maimonides. While there are various other works titled similarly, the title "Sefer Hamitzvot" without a modifier refers to Maimonides' work. It is a listing of all the commandments of the Torah, with a brief description for each. It originally appeared in Judaeo-Arabic under the title "Kitab al-Farai'd", and was translated into Hebrew by the Provençal rabbi Moses ibn Tibbon (first printed 1497) as well as by ibn Hasdai, in the 13th century. A new Hebrew translation from the original Judaeo-Arabic was made by the noted Yemenite scholar, Rabbi Yosef Qafih. Source: Wikipedia (en)
