Purpose Ethical entrepreneurship and financing models based on Islamic principles are insufficiently researched and discussed in the emerging plural economic landscape. So far, Islamic theorists have made commendable efforts in this direction. To fill the knowledge gaps, this study aims to explore more rigorously the interdependence of halal entrepreneurship and Islamic finance in creating a strong halal ecosystem. Design/methodology/approach Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology, a systematic literature review (SLR) of 33 articles from 2001 to 2024 was conducted to answer three research questions. Publications were obtained using purposive sampling from the Scopus database. They were selected based on the ranking of high-quality journals, global coverage relevance to research and base years of publications. Findings Three key findings emerged from the SLR using the PRISMA protocol. First, halal entrepreneurship and Islamic finance complement each other by providing Shari’ah-compliant financial instruments, fostering ethical practices, enhancing market reach and ensuring business operations adhere to Islamic principles, thereby creating a cohesive halal ecosystem. Second, the strategic integration of halal entrepreneurship and Islamic finance – through innovation, sustainability practices, Shari’ah-compliant products, effective marketing and regulatory support – promotes economic growth, social welfare and sustainable development within the halal ecosystem. Third, Maqasid-ul Shari’ah principles guide halal entrepreneurship and Islamic finance by ensuring ethical standards, promoting social justice, emphasizing sustainability and ensuring that business and financial practices benefit society and adhere to Islamic ethical standards. These findings aid in developing a theoretically grounded conceptual framework for future empirical investigation. Practical implications Practically, policymakers, Islamic financial institutions and halal entrepreneurs can leverage this integrated approach to drive economic growth, social welfare and sustainable development, aligning operations with Maqasid-ul Shari’ah to ensure ethical standards and societal benefits. In addition, the findings aid in developing a theoretically grounded conceptual framework for future empirical investigation, both theoretically and methodologically. Originality/value Given the paucity of studies in this multidisciplinary area, this paper offers new insights into the interdependence of halal entrepreneurship and Islamic finance, grounded in the finance–growth nexus theory and Maqasid-ul Shari’ah principles. Unlike other exploratory studies, this research presents a theoretically grounded conceptual framework, paving the way for future empirical investigations.
