People:
Those who has disbelieved their wealth and their children will never benefit them anything with Allah. And those are the ones who are the fuel of Hellfire.
[ali'-Imran, 3: 10]
Jinn:
And there are among us Muslims (in submission to Allah) and others who deviate from justice. And whoever accepts Islam has sought out the right path. As for those who deviate, they will be firewood for the Hellfire.
[al-Jinn, 72: 14-15]
Stones:
But if you cannot and of a surety you cannot then fear the fire whose fuel is men and stones, which is prepared for those who reject faith.
[al Baqarah, 2: 24]
O you who believe, save yourselves and your families from a fire whose fuel is men and stones, over which are appointed angels, stern and severe, who do not disobey Allah in what He orders them and who do precisely what they are commanded.
[al-Tahreem, 66: 6]
False Gods
Verily, you (unbelievers) and what you worship besides Allah are fuel for Hellfire, You will surely come to it. If those had (truly) been gods, they would not have come to it. But all will abide therein eternally.
[al-Anbiya, 21: 98-99]
And the Fierce Fire will be brought out before those straying in evil, and it will be said to them, Where are those you worshipped besides Allah? Can they help you or help themselves? Then they will be thrown into it (the Hellfire) on their faces they and those straying in evil and the soldiers of Iblees, all together.
[ash Shu'ara, 26: 91-95]
The Intensity of its Fire
Abu Hurairah (radiAllahu anhu) narrated: When Allahs Messenger (salAllahu alayhi wasalam) said,
Your ordinary fire is one of the 70 potions of the Hellfire, someone commented, O Messenger of Allah, would it (ordinary fire) not be sufficient (to burn the wrongdoers)? At that, Allahs Messenger (SAW) said, The Hellfire has 69 more portions than ordinary (worldly) fire, and all of them are as hot as this (worldly fire).
[Sahih al-Bukhari]
Verily, Allah has cursed the disbelievers and prepared for them a Blazing Fire. Dwelling therein forever, and they will find no protector or helper.
[al-Ahzab, 33: 64-65]
But he who is given his record behind his back will soon cry for destruction, and he will enter a blazing Fire.
[al Inshiqaq, 84: 10-12]
No, they deny the Hour (of the judgment to come), but We have prepared a blazing fire for such as deny the Hour. When it sees them from a far off place, they will hear its fury and its raging sigh. And when they are cast, bound, in chains, into constricted place therein, they will plead therein for destruction. Do not plead today for a single destruction; plead for destruction oft-repeated.
[al-Furqan, 25: 11-14]
The companions of the left hand what are the companions of the left hand? (They will be) in the midst of a fierce blast (of fire) and in boiling water.
[al Waqi'ah, 56: 41-42]
But, he whose scales are light his home will be a pit. And what will make you understand what that is? (It is ) a fire, blazing fiercely.
[al Qariah, 101: 8-11]
Soon will I cast him into Saqar (the Hellfire). And what will explain to you what Saqar is? It permits nothing to endure, and it leaves nothing alone, darkening and changing the color of man.
[al Muddaththir, 74: 26-29]
Their abode will be Hell. Every time it abates. We will increase for them the blaze (the fierceness) of the fire.
[al Isra, 17: 97]
Those are the ones, who have exchanged the Hereafter for the gains of this worldly life. The punishment will not be lightened for them, and they will not be aided.
[al Baqarah, 2: 86]
So taste, (the result of your deeds), for We will not increase you except in punishment.
[an Naba, 78: 30]
Anas (radiAllahu anhu) reported that the Messenger of Allah (salAllahu alayhi wasalam) said:
The most favored man among the dwellers of the Earth will be brought from among the people of the Fire on the Day of Resurrection. He will be dyed in the Fire but once, and then it will be said to him, O son of Adam, have you ever seen good at all? Has any pleasure ever come to you? He will say, No, by Allah, O Lord. Then the most miserable people in the world will be brought from the people of Paradise and will be dyed with the dye of Paradise. It will be said to him, O son of Adam, have you ever seen any misery, and has any hardship ever come to you? He will say, No, by Allah, O my Lord. No misery ever came to me, nor did I see any hardship.
[Muslim]
The Shade of Hell
The companions of the left hand what are the companions of the left hand? (They will be) in the midst of a fierce blast (of fire) and in boiling water and in the shades of black smoke nothing cool and nothing beneficial.
[Waqiah, 56: 41-44]
And woe that Day to the deniers (of truth). ([It will be said], Depart to a shadow [of smoke ascending] in three columns, [which yields] no shade of coolness and is of no use against the fierce blaze.
[Mursalat, 77: 28-31]
The Sparks of it's Fire
Indeed, it throws about sparks [as huge] as a palace, as if they were yellow camels.
[al-Mursalat, 77: 32-33]
The Names of Hell-Fire
Jahannam:
Truly Jahannam (the Hellfire) is lying in wait.
[an-Naba, 78: 21]

[Maarij, 70: 15-16]
Al-Hutamah: (Crusher which Smashes or Breaks to Pieces):
By no means! He will certainly be thrown into al-Hutamah. And what will make you understand what al-Hutamah is? It is the fire of Allah, kindled to a blaze, which mounts right to the hearts.
[al Humazah, 104: 4-7]
Saeer (the Burning Fire):
a group in Paradise and a group in Saeer.
[ash-Shura, 42: 7]

Soon will I cast him into Saqar. And what will explain to you what Saqar is? It permits nothing to endure and it leaves nothing alone, darkening and changing the color of man.
[al Muddaththir, 74: 26-29]

Al-Hawiyah (The Pit)
But he whose scales are light his home will be a pit. And what will make you understand what that is? (It is) a fire, blazing fiercely.
[al Qariah, 101: 8-11]
The Keepers of Hell
Those in the Fire will say to the keepers of Hell, Pray to your Lord to lighten for us the penalty for a day (at least). They will say, Did there not come to you your messengers with clear signs? They will say, Yes. They will reply, Then pray as you like. But the prayer of those without faith is not but in error.
[Ghafir, 40: 49-50]
O you who believe, save yourselves and your families from a fire whose fuel is men and stones, over which are (appointed) angels, stern and severe, and who do not disobey Allah in what He orders them and who do precisely what they are commanded.
[at-Tahreem, 66: 6]
Over it are nineteen. And We have not made the guardians of the Fire except angels. And We have made their number only as a trial for the unbelievers in order that the People of the Book may be certain and that the believers may increase in faith, and so that the People of the Book and the believers would not doubt, and that those in whose hearts is a disease and the unbelievers would say, What example does Allah intend by this? Thus does Allah leave to stray whom he pleases and guides whom He pleases. And none can know the soldiers of your Lord except He. And this is nothing other than a warning to mankind.
[Muddaththir, 74: 30-31]
