A shaitan or shaytan (Arabic: شَيْطَان, romanized: shayṭān; pl.: شَيَاطِين shayāṭīn; Hebrew: שָׂטָן; Turkish: Şeytan or Semum, lit. 'devil', 'demon', or 'satan') is an evil spirit in Islam,[2] inciting humans and jinn to sin by whispering (وَسْوَسَة, waswasa) in their hearts (قَلْب qalb).[3][4] According to Islamic tradition, though invisible to humans, shayatin are imagined to be ugly and grotesque creatures created from "Hellfire".[5][6](p21)
The Quran speaks of various ways the shayatin tempt humans into sin. They may teach sorcery, float below the heavens to steal the news of the angels, or lurk near humans without being seen. Several hadith tell of how the shayatin are responsible for various calamities that affect personal life. Both the hadith literature and Arab folklore usually speak of the shayatin in abstract terms, describing their evil influence only. According to hadith, during Ramadan they are said to be chained in Hell.
In Islamic theology, the influence of the shayatin on humans is elaborated as an internal struggle against the noble angels, often described in the invisible reality called alam al-mithal or alam al-malakut.
