Amīn al-Dawla Abu'l-Ḥasan Hibat Allāh ibn Ṣaʿīd ibn al-Tilmīdh (Arabic: هبة الله بن صاعد ابن التلميذ; 1074 – 11 April 1165) was a Christian Arab physician, pharmacist, poet, musician and calligrapher of the medieval Islamic civilization.
[3] He mastered the Arabic, Persian, Greek and Syriac languages.
Al-Tilmidh was a friend of the Muslim scientist al-Badīʿ al-Asṭurlābī with whom he frequently sided against Abu'l-Barakat.
[4] He compiled several medical works, the most influential being Al-Aqrābādhīn al-Kabir, a pharmacopeia which became the standard pharmacological work in the hospitals of the Islamic civilization, superseding an earlier work by Sabur ibn Sahl.
[3] His poetry included riddles: Abū al-Maʿālī al-Ḥaẓīrī quotes five of them, and a verse solution by al-Tilmīdh to another riddle, in his Kitāb al-iʿjāz fī l-aḥājī wa-l-alghāz (Inimitable Book on Quizzes and Riddles).
