Attributes of Satan: 1. Disobeyer i.e. Disobeyed Allaah May He be Glorified and Exalted. 2. Conspirator: Conspired against Adam and Eve. 3. Liar. Lied to Adam and Eve. 4. Arrogance. He's arrogant. He said something like I'm made of fire and Adam is made of clay I'm better and won't bow to him. I think a possessed person (demonic possesion) has these characteristics. Exorcists should look for these signs.
