This study examines how Islamic family ethics can reconstruct psychological well-being beyond conventional assessments of marital satisfaction and proposes an integrative framework for Muslim marital relationships. Using qualitative library research and an integrative literature review, the study synthesizes scholarship on Islamic family ethics, psychological flourishing, marital relationships, and the sociology of Islamic family law through thematic and conceptual analysis. The synthesis identifies three interconnected pathways: emotional mechanisms involving affection, compassion, and emotional security; moral mechanisms involving justice, dignity, autonomy, and accountability; and relational mechanisms involving reciprocal care, respectful communication, shared decision-making, and conflict resolution. These pathways suggest that marital satisfaction alone cannot adequately capture psychological well-being, particularly where unequal responsibilities or power imbalances undermine individual flourishing. The study proposes a four-component Islamic ethical–psychological framework linking ethical foundations (mawaddah, rahmah, 'adl, and mu'asharah bi al-ma'ruf), emotional and moral mechanisms, relational practices, and multidimensional well-being outcomes. Sociocultural expectations and gender relations are recognized as contextual influences on these proposed relationships. The framework contributes to Islamic family law sociology by connecting normative ethical principles with lived marital experiences and offers conceptual guidance for premarital education and culturally responsive family counseling. Its proposed mechanisms require further empirical validation across diverse Muslim communities.
