According to search-discovered classical Islamic scholarship, the angel Malik is the chief guardian of Hell (Jahannam), an imposing figure mentioned in the Quran in Surah Az-Zukhruf (43:77). Classical commentators like Ibn Kathir explain that Malik's role is to oversee the punishment of the disbelievers and to confirm the eternal nature of their state. The Hadith literature, particularly the narrations of the Prophet Muhammad's Night Journey (Isra and Mi'raj), describes Malik as a stern and severe angel who has never smiled since his creation, a reflection of his solemn duty. His name, which means 'king' or 'owner,' signifies his authority over Hell, which he exercises in perfect obedience to God's commands. The belief in Malik serves as a powerful reminder of divine justice and the accountability for one's actions in the afterlife.
