Iblis

In Islam, the devil is called Shayṭtān, (Arabic: شيطان‎‎, plural: شياطين shayāṭtīn) and refers to all evil forces under leadership of the archdevil known as Iblīs, who was cast out of heaven, after he refused to prostrate before Adam.

The primary characteristic of Iblis is hubris; not only did he deem himself a superior creation to Adam, he also demonstrated arrogance by challenging God'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."

The term Iblis (Arabic: إِبْلِيس‎‎) may have derived from the Arabic verbal root بَلَسَ (balasa, "he despaired"). Another possibility is that it is derived from Ancient Greek διάβολος (diábolos), also the ultimate source of English 'devil.' However, there is no consensus on the root of the term.The term Shaytan (Arabic: شَيْطَان‎‎) also has the same origin as Hebrew שָׂטָן (Sātān), source of the English Satan.
