The first volume to explore Muslim piety as a form of economy, this book examines specific forms of production, trade, regulation, consumption, entrepreneurship and science that condition - and are themselves conditioned by - Islamic values, logics and politics. With a focus on Southeast Asia as a site of significant and diverse integration of Islam and the economy - as well as the incompatibilities that can occur between the two - it reveals the production of a Muslim piety as an economy in its own right. Interdisciplinary in nature and based on in-depth empirical studies, the book considers issues such as the Qur'anic prohibition of corruption and anti-corruption reforms; the emergence of the Islamic economy under colonialism; 'halal' or 'lawful' production, trade, regulation and consumption; modesty in Islamic fashion marketing communications; and financialisation, consumerism and housing. As such, it will appeal to scholars of sociology, anthropology and religious studies with interests in Islam and Southeast Asia.
