Abstract
This study investigates the effect of Islam on efficiency of Muslim employees in multinational companies. The findings of the studies conducted to date examining the potential and actual impact of Islam in multinational setting indicates that although it seems that religion has no significant effect on multinational companies, but its internal effects such as internal and interpersonal conflicts with the type of activity of companies may be intensified. Moreover,these effects would be different based on the department of individual employees. For example, when the religious orientations of Muslims increase, their activities, according to the type of the product or service provided, in marketing sector of multinational companies maybe affected. As the products and services offered would have more moral dimensions and marketing activities would be based on general moral rules, not a particular religion, we may achieve more effective results and personal and interpersonal conflicts can be reduced.
