A scion of a family of Shīʿī theologians, he became known as the “wise man of Ḥillah.” He also studied philosophy with Naṣīr ad-Dīn aṭ-Ṭūsī (Ṭūsī, Naṣīr al-Dīn al-) (d. 1274), a noted philosopher of his time.Among al-Ḥillī's more than 500 scholarly works on the Islamic faith are the al-Bāb al-ḥādī ʿashar (Treatise on the Principles of Shīʿite Theology, 1928) and the Sharḥ tajrīd al-iʿtiqād. These are standard references on Twelver Shīʿī beliefs and are still used as textbooks in Iran.Attracted by the religious freedom of the Mongol Il-Khanid Dynasty (the descendants of Hülegü, who sacked Baghdad in 1258), al-Ḥillī emigrated to Iran in 1305. There he was responsible for converting Öljeytü (Öljeitü), the eighth Il-Khanid of Iran, from the Sunnī faith to Shīʿah. In 1305 Shīʿah was proclaimed the state religion of Iran. Al-Ḥillī was buried in Meshed.
