Yusuf ibn Tashfin
Under the Almoravids, some Jews prospered (although far more so under Ali III, than under his father Yusuf ibn Tashfin). Among those who held the title of "vizier" () or "nasih" () in Almoravid times were the poet and physician Abu Ayyub Solomon ibn al-Mu'allam, Abraham ibn Meïr ibn Kamnial, Abu Isaac ibn Muhajar, and Solomon ibn Farusal.
