Ali ibn Ibrahim al-Qummi
Abu al-Hasan Ali Ibn Ibrāhim al-Qummi was a 10th century Shi'a commentator and jurist. He lived during the time of the eleventh Shi'a Imam Hasan al-Askari. Many traditions in the famous book Al-Kafi were transmitted by him. Ibrāhim’s patronymic was “Abu al-Hasan” but he was also known as “al-Shaykh al-Aqdam”. He was the first to promulgate the “Kufan” traditions (Hadiths) in Qom and collected Hadith from many scholars. He wrote more than 15 books, famously his commentary Tafsir al-Qummi. He is said to have been one of the most important Imami Quran commentators. His other works include Akhbār Al-Quran, Nawadir al-Qur'an, al-Nasikh wa al-Mansukh(Abrogator and Abrogated books), al-Sharā'i' (Laws or revealed religions), and al-Tawhid wa al-shirk (Oneness of God and Polytheism). He died in 919 A.D.
