Islamic Aristotelian philosopher and physician of Jewish descent

to 1165 CE
Abu'l-Barakāt Hibat Allah ibn Malkā al-Baghdādī (c. 1080 – 1164 or 1165 CE) is an Islamic philosopher and physician of Jewish descent from Baghdad, Iraq.
Abu'l-Barakāt, an older contemporary of Maimonides, is originally known by his Hebrew birth name Baruch ben Malka and is given the name of Nathanel by his pupil Isaac ben Ezra before his conversion from Judaism to Islam towards the end of his life.
His writings include the anti-Aristotelian philosophical work Kitāb al-Muʿtabar ("The Book of What Has Been Established by Personal Reflection"); a philosophical commentary on the Kohelet; and the treatise "On the Reason Why the Stars Are Visible at Night and Hidden in Daytime".
Abu'l-Barakāt is an Aristotelian philosopher who in many respects follows Ibn Sina, but also develops his own ideas
He proposes an explanation of the acceleration of falling bodies by the accumulation of successive increments of power with successive increments of velocity.
His thought influences the Illuminationist school of classical Islamic philosophy, the medieval Jewish philosopher Ibn Kammuna, and the medieval Christian philosophers Jean Buridan and Albert of Saxony.
