The Lights of Revelation and the Secrets of Interpretation is a classic thirteenth-century commentary (tafsir) on the Qur'an. Drawing upon the works of Al-Zamakhshari and al-Razi, al-Baydawi carefully presents Mu'tazilite tafsir in a language acceptable to the orthodoxy of his time. A profoundly influential commentary across the Muslim world, this primary source is recommended for scholars of Qur'anic and Islamic studies.
