Judaism, Christianity, and Islam are referred to as the "Abrahamic religions." This is because Abraham is conventionally acknowledged as the first Jew - and believed to have established a covenant with God. This shared recognition of Abraham as the initial prophet is acknowledged across Judaism, Christianity, and Islam, earning them the collective term "Abrahamic religions." Though these belief systems differ from each other, some things that they share in common are: monotheism (the belief of one God); the importance of prayer; charity; and pilgrimage (PBS, 2002).
