Illiyin or Illiyun (Arabic: عِلِّيِّين, عِلِّيُّون‎, romanized: ʿilliyyīn, -ūn literally: heaven, upperworld) is a Quranic term referring to either the "most high" and "supreme" places above Jannah, i.e. the Garden of Eden or paradise, in the seventh heaven closest to the Throne of God (al-ʿArsh),[1][2] or, according to a different interpretation, a register for the blessed or record of the righteous (analogous to Sijjin),[3][4] which is mentioned in Surah al-Muṭaffifīn (83:18–20) of the Quran. The antithesis of Illiyin is Sijjin.[5]
