R. Ya’acov ibn Zur (signs Yavetz), (1673–1752), rabbi, scholar, and holy man was born in Fez. Among his teachers were R. Menahem Serero and R. Vidal Zarfati. Oppressive taxation induced the Yavetz to move to Meknes, where he became a member of the bet din of R. Judah ibn Attar (the uncle and teacher of the Ohr ha-Hayyim ha-Kadosh).

R. Judah b. Jacob ibn Attar, (known as "Rabbi al-Kabbir" (the great teacher); 1655–1733), was born in Fez and at a young age he was appointed head of the Moroccan dayyanim, after refusing to accept any remuneration for this function. He earned his living in trade and devoted his life to the well being of his coreligionists. In collaboration with his disciple, R. Jacob ibn Zur, he published the takkanot of the first Spanish exiles in Fez and drew up new regulations that continued to serve as the basis of Judeo-Moroccan jurisprudence. His published works include Minhat Yehudah on the Pentateuch (1940); customs and practices of Fez regarding terefot published in Mekor Hayyim (1897). Many responsa were published in Mishpat u-Zedakah le-Ya'akov (pt. 1–1894, pt. 2–1903) and others appear in works of various Moroccan rabbis. Many of his writings still exist in manuscript including a commentary on Midrash Rabbah. The Chidah devotes a lenghty description to him, where he describes him as a holy man whose name invokes miracles even after his demise.

R. Menahem b. David Seraro (1628–1701), teacher of the Yavetz, was a fiery preacher, was rabbi in Fez. An outstanding halakhic authority, he was the recipient of numerous queries concerning the takkanot of the megorashim (expellees) and their customs.
