This chapter explores the intersection of youth religiosityReligiosity and the halal (what is permissible according to Islamic principles) economy in Indonesia by focusing on young Muslims belonging to the transnational Salafi movement who are engaged in halalHalal entrepreneurship. Drawing on ethnographic fieldwork conducted in Jakarta from October 2021 to August 2024, it traces the shift from ideological hijrah—a spiritual transformation toward becoming better Muslims—to economic hijrahHijraheconomic hijrah, where religiosity is expressed through business practices aligned with Islamic principles. These young Salafis embrace a stricter interpretation of halal living, combining pietyPiety with economic aspirations through ventures in halal lifestyle businesses. The chapter situates these practices within broader debates on modernityModernity and “multiple modernities,” showing how SalafiSalafi halal entrepreneurship reflects both selective adaptation to and resistance against global capitalism. It argues that these practices are not merely self-fashioning projects but also forms of da’wa (proselytisation) and moral entrepreneurship. Highlighting the dynamic role of social media and invented traditions, it illustrates how young Salafis are reshaping Indonesia’s halal industry while constructing alternative moral economies. This chapter demonstrates that halal industry hype has been fuelled by the eagerness of urban young Muslims to align their economic pursuits with what they see as the true path of their religion.
