Jamāl ad-Dīn al-Ḥasan bin Yūsuf bin ʿAli ibn al-Muṭahhar al-Ḥillī (Arabic: جمال الدين الحسن بن يوسف الحلي; December 1250 – December 1325), known by the honorific title al-Allāmah al-Ḥillī (Arabic: العلامة الحلي, "The Sage of Hillah") was an Iraqi Arab scholar and one of the most influential Twelver Shi'i Muslim authors of all time. He was an expert in Twelver theology, a pioneering mujtahid, as well as the first scholar to be referred to with the title "Ayatullah". Al-Hurr al-Amili enumerated no less than 67 works by him. He is considered the first scholar to successfully disseminate Shia Islam widely in Persia.
