Abu al-Bayan ibn al-Mudawwar (sometimes referred to simply as ibn al-Mudawwar or, erroneously, as Mudawwar) (1101–1184) was a KaraiteJew living in Cairo during the twelfth century. He served as court physician to the last EgyptianFatimidcaliphs and later to Saladin, who pensioned him when he was sixty-three years old. He was replaced in his former position by, among others, Maimonides.
During the twenty years of his retirement his house was crowded with pupils; but he refused to see patients at their homes unless they were his friends. One day he was sent for by the emir Izz ad-Din abu-l-'Asakir Sultan ibn 'Izz ad-Dawla ibn Munqidh (uncle of the historian Usamah ibn Munqidh), who, on his arrival in Egypt, had fallen sick; ibn al-Mudawwar refused to go until requested to do so by al-Qadi al-Fadil, the private secretary of Saladin.
According to ibn Abi Usaibi'a, ibn al-Mudawwar left works on medical subjects, but they are no longer extant.
