of a philosophical work. The work "presented a serious philosophical alternative to, and criticism of, Ibn Sina". He also developed concepts which resemble several modern theories in physics. Abu'l-Barakāt also wrote a short treatise on the intellect, Kitāb Ṣaḥiḥ adillat al-naql fī māhiyyat al-ʻaql (صحيح أدلة النقل في ماهية العقل), which has been edited by Ahmad El-Tayeb. All that we possess in the way of medical writing by Abu'l-Barakāt are a few prescriptions for remedies. These remain in manuscript and are as yet unstudied. Legacy Abu'l-Barakāt's thought had a deep influence on Islamic philosophy but none on Jewish thought. His works were not translated into Hebrew, and he is seldom cited in Jewish philosophy, probably because of his conversion to Islam. The famous theologian and philosopher Fakhr al-Din al-Razi was one of Abu'l-Barakāt's eminent disciples. The influence of Al-Baghdadi's views appears especially in Al-Razi's chief work Al-Mabāḥith al-Mashriqiyyah (Oriental Discourses). Abu'l-Barakāt influenced certain conceptions of Suhrawardi.
