This work by Dr. Abu Ameenah Bilal Philips serves as an essential English introduction to the foundational principles and methodology of Quranic exegesis (Tafseer). It systematically outlines the authentic approach to interpreting the Quran, focusing heavily on the traditional sources: the Quran itself, the Sunnah (Prophetic traditions), the sayings of the Companions, and the views of the Successors. The book clarifies the prerequisites and necessary tools for a correct understanding of the Divine text, such as knowledge of the Arabic language, causes of revelation (Asbab an-Nuzul), and the distinction between the abrogating and abrogated verses (Nasikh wa Mansukh). It is widely used as a textbook, providing modern English-speaking readers with a clear, accessible framework rooted in classical Islamic scholarship to avoid misinterpretation.
