This scholarly work by Alaa Lafta Al-Kaabi delves into the profound linguistic influence of the pioneering grammarian Sibawayh on the field of Quranic exegesis (Tafsir). The study meticulously traces and analyzes how Sibawayh's grammatical theories and principles, famously compiled in his magnum opus 'Al-Kitab,' were utilized, debated, and applied by Quranic commentators throughout Islamic history. It illuminates the critical role that classical Arabic grammar played in interpreting the nuances of the sacred text, offering readers a deep appreciation for the intersection of linguistics and theology. The book is an essential resource for students of Arabic, linguistics, and Islamic studies.
