PurposeResearch on Islamic entrepreneurship (IE) is growing but with difficulty. After reviewing six IE models, several problematic inconsistencies were identified, which can be categorized into three: sporadic objectives of IE, diverging core components and inconsistent levels of analysis. This study aims to articulate a synthesized IE model.Design/methodology/approachAn Islamic critical realist synthesis is used by combining six IE models and situating them within an Islamic system of governance. Specifically, the Islamic governance conceptual matrix is used to offer an objective template.FindingsA synthesized model of IE within an Islamic system of governance comprises the following: the objectives of IE are not to be confined to only financial sustainability, but to achieve all five Maqās.id of the Sharī’ah (i.e. preservation and promotion of faith, life, intellect, posterity and wealth); models of IE should cover the individual, group, organizational, societal, state and international levels for comprehensiveness; tawhīd is crucial to distinguish between IE and conventional entrepreneurship; halal IE activities can be further categorized into obligatory, recommended, permissible and reprehensible; Islamic values are to be differentiated from cultural values; and both Islamic and cultural values shape IE and vice versa.Research limitations/implicationsLimited number of models of IE were included in this synthesis. Although the resulting synthesized model is extensive, additional models of IE can be built to extend or even challenge it.Originality/valueA novel model of IE within an Islamic system of governance is presented.
