al-Saʿdī
Al-Saʿdī explains that Hell lies in ambush, watching and waiting for the transgressors who denied resurrection and rejected the messengers — it is their final destination and abode. They will dwell there for unending successive ages (aḥqāb), each age followed by another without end, so the term does not imply eventual release but the perpetuity of their stay. They taste no coolness to relieve the fire's heat and no drink to quench their thirst — only scalding water (ḥamīm) and the dark, putrid discharge of the people of Fire (ghassāq). All of this, he stresses, is a recompense that perfectly matches their deeds: as their sins were the gravest, so their punishment is the most severe, in exact and just proportion.
