Comparative hadith-based Qur'anic exegesis is one of the principal approaches to understanding the Qur'an through the exegetical traditions of both Shi'a and Sunni schools. Despite its long-standing history, this approach still lacks a coherent and operational methodological framework for the collection, authentication, and analysis of exegetical narrations. The absence of a systematic methodology has often led to subjective interpretations and inconsistent findings in Qur'anic studies. Employing a descriptive-analytical method and drawing upon the major exegetical and hadith sources of both traditions, the present study proposes a comprehensive methodological framework for analytical comparative hadith-based exegesis. The findings demonstrate that this approach consists of three interrelated stages. The first stage involves the comprehensive collection of explicit and implicit exegetical narrations from authoritative Shi'a and Sunni sources. The second stage focuses on evaluating the authenticity of these narrations through source criticism and textual as well as isnād-based assessment in accordance with the methodological principles of each school. The third stage comprises semantic analysis at three complementary levels: intratextual, intertextual, and extratextual. Intratextual analysis examines the lexical, propositional, and linguistic structures of the narrations; intertextual analysis investigates their relationship with the Qur'an, the Prophetic tradition, and other relevant narrations; and extratextual analysis draws upon historical, cultural, theological, and rational evidence to identify the intended meaning of the infallible authorities and to provide a well-founded interpretation of the Qur'anic text.
