We conclude from the above five verses that the punishment in Hell can be eternal or permanent just as the bounties of Paradise are never ending. Those who have taken to believing that the punishments will cease one day have no alternate but to resort to conjectures after seeing the above proofs.
It is true that there are some difficulties in believing the punishment to be never ending even if it is for a particular group in Hell but we can such difficulties through logic and we should never deny the literal meaning of the verses.
