Gustave Doré: depiction of Satan

Satan, in the three major Abrahamic religions (Judaism, Christianity, and Islam), the prince of evil spirits and adversary of God. Satan is traditionally understood as an angel (or sometimes a jinnī in Islam) who rebelled against God and was cast out of heaven with other “fallen” angels before the creation of humankind. Ezekiel 28:14–18 and Isaiah 14:12–17 are the key Scripture  passages that support this understanding, and, in the New Testament, in Luke 10:18 Jesus states that he saw Satan fall like lightning from heaven. In all three major Abrahamic religions, Satan is identified as the entity (a serpent in the Genesis account) that tempted Eve to eat the forbidden fruit in the Garden of Eden and was thus the catalyst for the fall of humankind.
