The title of this book, Usool at-Tafseer, essentially refers to the branches of knowledge necessary for providing an accurate interpretation of the Quranic texts, such as Arabic grammar and syntax, Arabic literature and Quranic sciences (Uloom al-Quran).
Familiarity with modern fields of learning, like the pure sciences and social sciences is also necessary for a commentator in this era to make the Quraanic explanations relevant to human society.
This book addresses the actual step-by-step methodology of interpreting Quran to ensure that interpretations are not merely the result of human whims and fancies.
