This study examines the profound engagement of the Imams of Ahl al-Bayt (as) and their Shiʿa followers with the Qur’an and its sciences, tracing their intellectual and spiritual contributions from the formative centuries of Islam to the contemporary era. The research highlights how Shiʿa scholarship developed a comprehensive approach to Qurʾanic studies—spanning exegesis (tafsīr), recitation (qirāʾāt), grammar, rhetoric, abrogation (nāsikh wa’l-mansūkh), and the study of revelation contexts (asbāb al-nuzūl)—while maintaining a firm theological commitment to the Qurʾan’s authenticity and divine preservation. The article situates the Imams of Ahl al-Bayt (as)as divinely guided interpreters whose teachings form the cornerstone of Shiʿa Qurʾanic understanding. By exploring both historical narratives—such as Imam ʿAlī’s compilation of the Qurʾan—and doctrinal positions—such as the rejection of taḥrīf (textual alteration)—the study underscores the distinctive yet integrative character of Shiʿa engagement with the Qurʾan. It concludes that Shiʿa contributions have significantly enriched the broader field of Qurʾanic sciences, offering unique hermeneutical, linguistic, and spiritual insights that continue to influence Islamic thought.
