Monotheism—the belief that there is only one deity—is a foundational tenet of the Abrahamic religions, which alike conceive God as the all-powerful and all-knowing deity from whom Abraham received a divine revelation, according to their respective narratives. The most prominent Abrahamic religions are Judaism, Christianity, and Islam. They—alongside Samaritanism, the Druze Faith, the Baháʼí Faith, and Rastafari—all share a common belief in the Abrahamic God. Likewise, the Abrahamic religions share similar features distinguishing them from other categories of religions:
- all of their theological traditions are, to some extent, influenced by the depiction of the God of Israel in the Hebrew Bible, who is explicitly named Yahweh in Hebrew and Allah in Arabic;
- all of them trace their roots to Abraham as a common genealogical and spiritual patriarch.
In the Abrahamic tradition, God is one, eternal, omnipotent, omniscient, and the creator of the universe. God is typically referred to with masculine grammatical articles and pronouns only, and is further held to have the properties of holiness, justice, omnibenevolence, and omnipresence. Adherents of the Abrahamic religions believe God is also transcendent, meaning he is outside of both space and time and therefore not subject to anything within his creation, but at the same time a personal God: intimately involved, listening to individual prayer, and reacting to the actions of his creatures.
