This study examines the etiquette of Muslims toward family members of different religious beliefs from the perspective of the hadiths of the Prophet Muhammad (peace be upon him). Differences in religious beliefs within a family do not necessarily constitute a reason to sever kinship ties. Islam continues to emphasize the importance of maintaining family relationships, treating others kindly, showing respect, providing assistance in permissible matters, and treating non-Muslim family members humanely. Nevertheless, such relationships have certain boundaries, particularly in matters of faith and worship. This study employs a library research method with a qualitative approach. The primary sources consist of the hadiths of the Prophet Muhammad related to Muslim relationships with non-Muslim family members, while supporting sources include hadith commentaries, books, journal articles, and other relevant literature. The analysis was conducted thematically by collecting hadiths related to the topic, conducting takhrij, examining the authenticity and quality of the hadiths, understanding their meanings through the explanations of Islamic scholars, and relating them to relevant verses of the Qur’an. The findings indicate that the hadiths of the Prophet provide balanced guidance: Muslims are instructed to maintain family relationships and treat non-Muslim family members kindly, but they are not permitted to follow invitations or practices that contradict tawhid and the principles of Islamic teachings. Thus, etiquette toward non-Muslim family members reflects a balance between steadfastness in faith and the fulfillment of humanitarian obligations
