The purpose of this paper is to analyze the impact of Islamic law and national cultures on the ethical perceptions and behavioral intentions of Muslim Indonesians in buying modern funeral services. A questionnaire was distributed among Muslim respondents who were doing their routine weekly Friday prayers in Sunda Kelapa, one of biggest mosques in Central Jakarta. Based on a total sample of 103 responses, structural equation modeling was used to test the research hypotheses. This research used the theory of reasoned action proposed by Ajzen to analyze behavioral intentions. Since the behavioral intentions were influenced by the ethical perceptions, the Hofstede national culture was deemed to play a significant role. The data analysis further suggested that the behavioral intentions in buying modern funeral services were strongly influenced by Islamic law (MUI Fatwa), Indonesia culture dimensions, and the ethical perceptions among Muslim Indonesians. Both Islamic law and Indonesian national culture (as a collectivist country) play a significant role in creating ethical perceptions and influence Muslim behavioral intentions in regard to buying modern funeral services.
