1. Jahannum
They said, 'Do not go forth in the heat." Say, "The fire of Hell is more intensive in heat" - if they would but understand.
Qur’an | 9:81
The gate is called jahannum cause the fire will burn the faces of men and women who enters it. And faces will be sullen. And in the Noble Qur'an Allah says:
Every time their skins are roasted through We will replace them with other skins so they may taste the punishment. Indeed, Allah is ever Exalted in Might and Wise.
-Quran | 04:56
The ironic thing is this is the lightest punishment that one can receive.
2. Ladha (Fierce blaze)
The second level of hell is called Ladha because the fire will eat away their body parts one by one. Both internally and externally. It will invite those who abandoned Tawheed,
And turn away from the following truth, heedless of it and gathered wealth and refused to spent it in the cause of Allah.
No! Indeed, it is the Flame [of Hell],
Quran | 70:15
3. Saqar
This is the third level of hell, it will eat up.the flesh of human beings. And not his bones but listen to what Allah mentioned about those who enter this particular level of hell.
I will drive him into Saqar. And what can make you know what is Saqar? It lets nothing remain and leaves nothing [unburned].
Qur'an | 74:26-29.
[Who will be] in gardens, questioning each other.
About the criminals, And asking them “what put you into saqar.? They will say we were not to those who prayed, nor did we used to feed the poor. And we used to deny the day of recompense. Untill there came to us the certainly.
-Qur'an | 74:40-47.
4. Al-Hutamah (Crushing Fire)
Fourth gate of hell is Al-Hutamah, this hell will shatterel the bones of human beings, and burn the heart and other internal organs. The fire would start at his feet and burn all the way through untill it reaches the heart.
They will surely be thrown into the Al-Hutamah (i.e Crushing fire). & what can make you know what is the crusher.? It's the fire of hell externally fueled. Which mounts directed at the Heart. Indeed Hell fire will be closed down upon them in extended coloums.
-Qur’aan | 104:4-9
5. Jaheem.
[ Allah will say], "Seize him and shackle him. Then into hellfire drive him.Then into a chain whose length is seventy cubits insert him." Indeed, he did not used to believe in Allah, the Most Great, Nor did he encourage the feeding of the poor.
-Qur’an | 69:30-34
6. Sa’eer (The blazing fire)
Sixth level of gell is sa'eer, and in it there are 300 castles and in each castle there are 300 houses and each house there are 300 types of punishments.
A party will be in Paradise and a party in the sa'eer (The blazing fire)
Qur'an | 42:07.
And they will say, "If only we had been listening or reasoning, we would not be among the companions of the Blaze." And they will admit their sin, so [it is] alienation for the companions of as sa’eer.
-Quran | 67:10-11
7. Al-Haawiya.
Seventh level of gate is Al-Haawiya, and whoever enters this level gate will never comes out. And Allah swt says that the fire will embrace him/her like a mother embraces her child.
“But as for one whose scales are light, then the Haawiya will embrace him like mother embraces her child. And what will make you know, What Al-Hawiya is? It's a kindled fire burning hot.”
-Qur’an | 101:8-11
In the another verse Allah says:
“And we will call the zabaaniya (i.e angel who guard the hell fire.
-Qur'an | 96:18.
The hands of the zabaaniya like iron when they strike one of those in the hell fire one time with their hands and they let out a scream so loud, that both the jinn and mankind can hear.
Forgiveness and protection from Hell:
رَبَّنَآ إِنَّنَآ ءَامَنَّا فَٱغْفِرْ لَنَا ذُنُوبَنَا وَقِنَا عَذَابَ ٱلنَّارِ
Those who say, "Our Lord, indeed we have believed, so forgive us our sins and protect us from the punishment of the Fire,"
-Quran | 3:16
