Jahanam

Jahanam has 7 gates:

“Indeed the hell fire is the dwelling place of them all. It has seven gates and within each gate there is an appropriate punishment for each inhabitant…” (Hijr: 44)

4 gates of Jahanam are described below: Jahanam, Ladah, Saqar, Al- Hutamah

the first level contains the least amount of heat and the least amount of punishment compared to all of the other levels of Jahanam. People in this levels faces and flesh will be burned off and when the flesh is burnt off, Allah will make new flesh so it can burn again
“Every time the fire eats away their flesh We will replace it with new flesh so they can taste the punishment…” (Surah An-Nisaa’:56)

This fire will eat you internally and externally and burn each of your organs one by one until it destroys your whole body.
“There is no way out for them, except the Ladha (i.e. Fierce Blaze) will certainly scorch the inward organs and the outward flesh! It will invite everyone who turned away from following the truth, heedless of it and gathered wealth but refused to spend it in the cause of Allah…” (Ma’arij:15)

In this level of Jahanam the fire will completely eat someone’s flesh but not their bones for a number of reasons
“We were not of those who used to pray and we didn’t feed the poor and we used to talk vainly with those who talked vain talk and we used to deny the Day of Recompense until death came to us and we saw the reality of all that we denied” Quran 74:40-47

This is the absolute worst level this level according to the Quran says that “Al-Hawwiyah is the level in which kindled fire will embrace the sinner as a mother embraces her son.” And once in this level no dinner will be realized from it. It lies in pitch black darkness
The hands of the sinners will be bound to their necks and their necks to their legs.
Angels called Zabanniyah will stand in them and the angels hands are made of iron so they can use it to beat them.
