Sijjin and ` illiyin
كَلَّا إِنَّ كِتَابَ الْفُجَّارِ لَفِي سِجِّينٍ (Never! [ i.e. they should never forget that Day.] Indeed the Record of Deeds of the sinners is in sijjin. [ 83:71' The word sijjin is derived from sajana which means to 'imprison in a narrow place'. According to Qamus, the word sijjin means 'eternal imprisonment'. Traditions indicate that sijjin is a special place where the souls of the non-believers are kept, and in the same place, the Record of the evil deeds of every wicked person is kept separately. It is also possible that in this there is a consolidated book in which the deeds of all the non-believers of the world are recorded.
Where is this place? According to a lengthy hadith reported by Sayyidna Bara' Ibn ` Azib ؓ ، the Holy Prophet ﷺ has said that sijjin is beneath the seventh level of the earth, and ` illiyin is in the seventh heaven beneath the Divine Throne. [ Baghawi, and Ahmad etc., as quoted by Mazhari ]. According to certain Traditions, sijjin is the seventh earth which contains the souls of the disbelievers, and ` illiyin is the seventh heaven which contains the souls of the believers.
The Locale of Paradise and Hell
Baihaqi has recorded a narration from Sayyidna ` Abdullah Ibn Salam ؓ that Paradise is in the heaven, and Hell is in the earth. Ibn Jarir cites in his commentary on the authority of Sayyidna Mu'adh Ibn Jabal ؓ a narrative of the Holy Prophet ﷺ ، according to which he was asked about the meaning of the following verse:
وَجِيءَ يَوْمَئِذٍ بِجَهَنَّمَ
'and Jahannam (Hell), on that day, will be brought forward, [ 89:23] '
The Holy Prophet ﷺ was asked from where the Hell be brought forward? He replied: "From the seventh earth." These narratives indicate that Hell will be brought forward from the seventh earth. It will suddenly flare up there, and all the oceans will join its blazing fire, and come forward in full view of all. This interpretation is reconcilable with narratives that define sijjin as the name of a place in Hell. [ Mahari ]. And Allah knows best!
