Jinn are mentioned several times in the Quran and one chapter of the Quran is called “The Jinn”. What are these Jinn? According to the Quran, Jinn are created from a smokeless fire (Quran 55:15). They are part of the unseen world, that is they are spiritual beings (Quran 7:27). Jinn are different from angels in that Jinn have free will to choose to obey or disobey God (Quran 72) and angels always serve God. Muslim scholars are divided on whether Iblis (Satan) was originally an angel, but in Quran 18:50 it says Iblis was “of the Jinn”. Jinn have supernatural abilities such as great speed, power, and skill (Quran 27:38-40). But in Islam Jinn are also like humans in some ways. They can eat, drink, marry, have sexual relations with people, have children, and die. They can appear in a human or animal body (Hadith al-Anfaal 8:48). In Quran 46:29-32 and 6:130, Jinn can be either Muslim (good) or non-Muslim (evil). Some Jinn are said to have helped Solomon (Quran 27:17,40). But in popular Islam, Jinn are almost always evil. They possess people, causing them to speak or act against their will. They cause sickness, seduce men, deceive people, and generally cause harm.
According to the Bible, there are no beings that are part spirit and part human. Both fallen and holy angels can assume human form, but they are not part human (Genesis 6; Luke 24:1-6). Spirit beings are divided into angels that serve God (Psalm 91:11) and evil spirits that fight against God and His followers (fallen angels, demons – Ephesians 6:12). Other than angels and evil spirits, the Bible does not contain spirit beings that can be either good or evil.
