Rabbi Yitzchak Alfasi (the Rif) and the Sefer HaHalachot
A scholar from Fez creates the 'little Talmud' — a digest keeping only what is settled in practice; the book becomes the foundation of all later halachah.
Rabbi Yitzchak ben Yaakov HaKohen, called Alfasi after the city of Fez, was born in 4773 and taught for most of his life in North Africa. At seventy-five, denounced to the authorities, he fled to Spain and headed the yeshiva of Lucena, where his students included Rabbi Yosef ibn Migash, later the teacher of Maimonides' father.
His work is the Sefer HaHalachot, popularly the 'little Talmud.' The Rif went through every tractate of practical relevance and kept only what governs action: he removed the aggadah, the laws of the Temple and purity, the rejected opinions, and decided disputed cases himself in a few words. The result was a book one could live by, yet it preserved the Gemara's own language and structure, so the student never lost contact with the source.
Maimonides said the Rif's code had displaced every halachic work before it and that he agreed with it on almost everything. A literature grew around it — the Raavad's criticisms, the commentaries of the Ran and Rabbeinu Yonah, the Rosh's rulings. In printed editions of the Talmud the Rif appears after each tractate, and his is one of the three voices by which Rabbi Yosef Karo decided the law.
