Abraham (originally Abram) is the common Hebrew patriarch of the Abrahamic religions, including Judaism, Christianity, and Islam. In Judaism, he is the founding father of the special relationship between the Jews and God; in Christianity, he is the spiritual progenitor of all believers, whether Jewish or non-Jewish; and in Islam, he is a link in the chain of Islamic prophets that begins with Adam and culminates in Muhammad. As the namesake of the Abrahamic religions, Abraham is also revered in other Abrahamic religions, such as the Druze faith and the Baháʼí Faith.
