In Islam, the Devil is known as Iblīs (Arabic: إبليس‎‎, plural: ابالسة abālisah), Shayṭān (Arabic: شيطان‎‎, plural: شياطين shayāṭīn) or Shaitan. The primary characteristic of the Devil is hubris; not only did he deem himself a superior creation to Adam, he also demonstrated arrogance by challenging Allah's judgment in commanding him to prostrate. His primary activity is to incite humans and jinn to commit evil through deception, which is referred to as "whispering into the hearts". The Quran mentions that Satans are the assistants of those who disbelieve in God: "We have made the evil ones friends to those without faith."
