Word: IBLIS

Iblis is the primary devil in Islam.  It appears in the Qur'an as the devil who refuses to bow down before Adam.  In Islam, Iblis represents more than just an evil being.  Iblis is a culmination of all things that are evil and wrong in the world.  He is satan and the devil to all Christians.  He is more than just an idea or a spirit.  He is given a name and it is even capitalized to give the devil more of a human-like quality.  It makes him more real and threatening than just being a serpent or spirit.  Dictionary.com defines Iblis as the chief of the wicked Jinn.  All other information is from http://www.babylon.com/definition/Iblis/English.
