The Devil (from Greek: διάβολος or diábolos slanderer or accuser) is, according to Christianity and Islam, the primary opponent of God. Christianity identifies the Devil ("Satan") with the Serpent who tempted Adam and Eve to eat the forbidden fruit, and describes him as a "fallen angel" who terrorizes the world through evil, is the antithesis of Truth, and shall be condemned, together with the fallen angels who follow him, to eternal fire at the Last Judgement. Islam identifies the Devil ("Shaitan") with all those who oppose Allah. Some non-Abrahamic religions contain figures similar to the Devil, such as the Buddhist demon Mara and the Zoroastrian spirit Angra Mainyu.
