Surah Al-Mutaffifin Verse 7

6013 This is a word from the same root as Sijn, a Prison. It rhymes with and is contrasted with "Illiyin in verse 18 below. It is therefore understood by many Commentators to be a place, a Prison or a Dungeon in which the Wicked are confined pending their appearance before the Judgement Seat. The mention of the Inscribed Register in verse 9 below may imply that Sijjin is the name of the Register of Black Deeds, though verse 9 may be elliptical and may only describe the place by the significance of its contents.
