Iblīs, in Islam, the personal name of the Devil, possibly derived from the Greek diabolos. Iblīs is also referred to as ʿAduw Allāh ( “Enemy of God”), al-Aduw (“Enemy”), or, when he is portrayed as a tempter, al-Shayṭān (“Demon”). Worshiping God for thousands of years, Iblis ascended to the surface, whereupon, thanks to his pertinacious servitude, he rose until he reached the company of Angels in the seventh heaven. When God created Adam and taught him the "names of all things" , then ordered the Angels to bow down, Iblis, being a jinn created from fire, refused, and disobeyed God, leading to his downfall.
