Every religion has some upside if you look hard enough. But the Quran's verses on punishment in Hell often seem more general than that, and the Quran relishes in threatening that punishment.
For instance, 'Who does more wrong than those who fabricate lies against Allah or deny His revelations? They will receive what is destined for them, until Our messenger-angels arrive to take their souls, asking them, “Where are those ˹false gods˺ you used to invoke besides Allah?” They will cry, “They have failed us,” and they will confess against themselves that they were indeed disbelievers."'
And, "Surely those who receive our revelations with denial and arrogance, the gates of heaven will not be opened for them, nor will they enter Paradise until a camel passes through the eye of a needle. This is how We reward the wicked. Hell will be their bed; flames will be their cover. This is how We reward the wrongdoers."
And it goes on and on and on and on about these punishments.
