In Islamic theology, Iblis (إبليس) is the personal name of the being from the Jinn who was cast out from Allah's grace due to his arrogant refusal to obey a divine command. The Quran narrates across several chapters that when Allah created Adam, He commanded the angels (and Iblis who was in their company) to prostrate before him. All obeyed except Iblis. According to classical scholars like Ibn Kathir and Al-Tabari, the root of Iblis's disobedience was kibr (arrogance), as he argued his own superiority based on his creation from fire versus Adam's from clay. The name Iblis itself is often linked by scholars to the Arabic root 'balasa' (بلس), meaning 'he despaired,' signifying his despair of Allah's mercy. Following his expulsion, he was given respite until the Day of Judgment to become the primary tempter of humanity, and in this role, he is most often referred to as Ash-Shaytan (The Satan). The Quran explicitly clarifies in Surah 18:50 that he "was of the Jinn," a race of beings created with free will, which explains his capacity to disobey, unlike the angels. His story serves as the ultimate Quranic warning against the perils of arrogance and the critical importance of absolute submission to the will of Allah.
