The circular economy (CE) has attracted growing scholarly and policy attention as a response to unsustainable linear consumption, yet adoption of circular practices, including second-hand purchasing, repair, and reuse, remains limited in emerging Muslim-majority economies. Social stigma and status concerns are established barriers to CE adoption, but the role of religious values in offsetting these barriers has received limited attention. This study systematically maps the fragmented literature on CE adoption barriers, social face consciousness, and Islamic consumption ethics through a systematic literature review integrated with bibliometric analysis following PRISMA 2020 guidelines. Six search strings applied to Scopus and Web of Science produced 145 initial records, of which 25 articles met the inclusion criteria for thematic synthesis; bibliometric analysis covered a corpus of 110 records using publication trend, citation, keyword co-occurrence, and geographic distribution analysis. The findings reveal three largely disconnected research clusters, CE behavior and adoption barriers, social face consciousness and status-oriented consumption, and Islamic consumption ethics and sustainability, and show that research rarely examines how religious values interact with social stigma in shaping CE adoption. This study contributes by identifying these structural gaps and proposing an integrative conceptual framework linking Islamic consumption ethics, social face consciousness, and CE adoption intention and behavior, offering a research agenda for advancing CE scholarship in emerging Muslim-majority markets.
