Majma‘ al-Bayan fi-Tafsir al-Qur'an (Arabic: مجمع البيان في تفسير القرآن) is a tafsir by the 12th century Imami scholar and author Shaykh Tabarsi.
This commentary is a comprehensive classical tafsir. Tabarsi was a man of great erudition. He was a master of Arabic and a noted theologian and jurist.[1]
The work is considered one of the most authoritative Imami Qur'an commentaries. Al-Tabrisi's method is to take up one group of verses at a time and discuss qira’at, language and grammar before providing a detailed commentary on the text, based on both Sunni and Shi‘i sources and incorporating his own views. His commentary for each passages are divided into five sections: introductory discourse, reading guide, language discourse, revelation and circumstances surrounding it, and meaning[2]
