Muhammad ibn Sa'id al-Tamimi (Arabic: أبو عبد الله محمد بن سعيد التميمي), (died 990), known by his kunya, "Abu Abdullah," but more commonly as Al-Tamimi, the physician, was a tenth-century physician, who came to renown on account of his medical works. Born in Jerusalem, Al-Tamimi spent his early years in and around Jerusalem where he studied medicine under the tutelage of two local physicians, Al-Hasan ibn Abi Nu'aym, and a Christian monk, Anba Zecharia ben Thawabah. Al-Tamimi possessed an uncommon knowledge of plants and their properties, such that his service in this field was highly coveted and brought him to serve as the personal physician of the Ikhshidid Governor of Ramla, al-Hassan bin Abdullah bin Tughj al-Mastouli, before being asked to render his services in Old Cairo, Egypt.
