ḤASDAI (ḤISDAI), ABU AL-FAḌL BEN JOSEPH IBN:
Jewish convert to Islam; lived at Saragossa in the second half of the eleventh century. Ibn Abi 'Uṣaibia ("'Uyun al-Anba fi Ṭabaḳat al-Aṭibba") pompously calls him a descendant of the prophet Moses. He relates further that Ḥasdai was an excellent poet, an orator, a clever logician and physician, and was well versed in mathematics and astronomy.
