Amën al-Dawla Abu'l-Ḥasan Hibat AllÃÂh ibn á¹¢aÿëd ibn al-Tilmëdh (; 1074 â 11 April 1165) was a Christian Arab physician, pharmacist, poet, musician and calligrapher of the medieval Islamic civilization.
Ibn al-Tilmidh worked at the ûAá¸Âudë hospital in Baghdad where he eventually became its chief physician as well as court physician to the caliph Al-Mustadi, and in charge of licensing physicians in Baghdad. He mastered the Arabic, Persian, Greek and Syriac languages. Al-Tilmidh was a friend of the Muslim scientist al-Badëÿ al-Asá¹ÂurlÃÂbë with whom he frequently sided against Abu'l-Barakat.
He compiled several medical works, the most influential being Al-AqrÃÂbÃÂdhën 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. His poetry included riddles: Abà « al-MaÿÃÂlë al-ḤaáºÂërë quotes five of them, and a verse solution by al-Tilmëdh to another riddle, in his KitÃÂb al-iÿjÃÂz fë l-aḥÃÂjë wa-l-alghÃÂz (Inimitable Book on Quizzes and Riddles).
