An Abrahamic religion is a religion whose followers believe in the prophet Abraham and his sons/grandsons to hold an important role in human spiritual development. The best known Abrahamic religions are Judaism, Christianity and Islam. Smaller religious traditions sometimes included as Abrahamic religions are Samaritanism, Druze, Rastafari, Yazidi, Babism, Bahá'í Faith. Mandaeism is also sometimes included as an Abrahamic religion, but this is actually inaccurate as Mandaeans believe that Abraham was a false prophet.
True Abrahamic religions are monotheistic (relating to or characterized by the belief that there is only one God). They also all believe that people should pray to and worship God often. Throughout monotheistic religions, the Abrahamic religions have the world's largest number of followers. They are also all ethical monotheistic religions meaning they have a certain set of rules that they have to follow.
