The opening as it read in 2025

Iraqi Twelver Shia theologian (c. 948–1022) Abu 'Abd Allah Muhammad ibn Muhammad ibn al-Nu'man al-'Ukbari al-Baghdadi , known as al-Shaykh al-Mufid ( Arabic : الشیخ المفید ) and Ibn al-Mu'allim (c. 948–1022 CE), was a prominent Iraqi Twelver Shia theologian . His father was a teacher ( mu'allim ), hence the name Ibn al-Mu'allim. The title "al-Mufid" was given to him either by Muhammad al-Mahdi , the twelfth Shia Imam, or by al-Rummani, a Mu'tazilite scholar, after a conversation with him. The leader of the Shia community, he was a mutakallim , theologian, and Shia jurist. He was taught by Al-Shaykh al-Saduq , Ibn Qulawayh , Abu Abdallah al-Basri and al-Rummani, and Sharif al-Murtaza and Shaykh Tusi were among his students. Only 10 of his 200 works have survived, among which are Amali , Al-Irshad , Al-Muqni'ah , and Tashih al-Itiqadat . Qurānic Christians : an analysis of classical and modern exegesis (digital ed.).
