Ali ibn Yusuf al-Ilaqi
Muḥammad ibn Yusuf al-Ilāqī was an eleventh-century Persian physician from Khorasan.
Contrary to Carl Brockelmann's information, Sharaf al-Zamān Muḥammad ibn ʿAlī al-Īlāqī of Bākharz, who was most probably active in Balkh, was not a figure of the 6th/12th century. He did not die in 536/1141 but most probably around 460/1068 and should be counted among Avicenna's direct students. Al-Ilāqī produced an epitome of the first book of the Canons of Medicine by Avicenna which was known under various titles: Kitāb al-Fuṣūl al-Ilāqiyya and Kitāb al-asbāb wa-al-`alāmāt. Al-Ilāqī's greatly abbreviated version of the first book of the Canon was very popular, and many copies have survived.
