Death is a feature that unites people all around the world and represents one of the core questions in religion and philosophy. The connection between religion and death is very strong. Numerous studies have proven that the fear of death is one of the most common fears, and religion has a strong influence on coping with the anxiety that occurs due to the fear of death. Religious customs related to death were created in different times and in different circumstances, so different beliefs and meanings of the concept of death were created. Christianity, Islam and Hinduism are major world religions that contain different religious practices and beliefs. Modern societies are increasingly becoming multicultural and multi-religious, which is reflected in the practice of social work and work in palliative care and leads to a greater need to provide effective and culturally sensitive care. It is necessary for social workers in palliative care to be familiar with different religions and to be aware of the role that religion plays in people's lives. Knowing the characteristics, beliefs and traditions of the world's major religions can significantly improve the experience of patients at the end of life, as well as lives of their families and religious communities.
