سورة الواقعة

Imam Sadiq (peace be upon him): These two verses were revealed concerning our friends and our enemies: فَأَمَّا إِن کَانَ مِنَ المُقَرَّبِینَ، فَرَوْحٌ وَ رَیْحَانٌ [And if he is one of those brought near, then comfort and fragrance] — meaning in his grave. And جَنَّةُ نَعِیمٍ [a garden of bliss] — meaning in the hereafter. And أَمَّا إِن کَانَ مِنَ المُکَذِّبِینَ الضَّالِّینَ فَنُزُلٌ مِنْ حَمِیمٍ [But if he is one of the rejecters, the erring ones, then an entertainment of boiling water] — meaning in his grave. And تَصْلِیَةُ جَحِیمٍ [and burning in Hell] — meaning in the hereafter.

Imam Ali (peace be upon him): But when those who escorted him depart and the mourners return, he is laid in the pit of his grave, whispering in sorrow at the shock of the questioning and the stumbling of the trial. And the greatest calamity there is the descent of the boiling water and the burning of Hell, and the blazing of the flame and the roaring of its inhaling — no respite that gives rest, no ease that removes pain, no strength that wards off the punishment, no death that delivers him from all this suffering, and no slumber that dispels his grief. He is caught between the varieties of deaths and the hours of manifold punishment.
