This paper explores the relationship between the Islamic religion and the level of socially responsible business conduct (SRBC) of Islamic entrepreneurs. The authors find that the common ideas of SRBC correspond with the view of business in Islam, although there are also some notable differences. They also find that Muslim entrepreneurs attach a higher weight to specific elements of SRBC than do non‐Muslims. However, they also find that Muslims are less involved with applying SRBC in practice than non‐Muslim managers.
