Allah has warned us in His Book about the Hellfire and has informed us about the different types of punishments it will have, to the extent that one's heart splits due to fear. Allah has informed us about its torment due to His mercy, so that we would therefore fear and avoid it.
Read attentively the verses in the Book of Allah that address the description of the Hellfire, perhaps it will be a reminder for you; perhaps they will cause you to repent before it is too late - before punishment strikes suddenly and you find nobody to support or aid you; perhaps they will make you realise the great success you will attain by following this message delivered by this great man.
Its chains: The Hellfire contains chains, as Allah says (what means): "Indeed, We have prepared for the disbelievers chains and shackles and a blaze."[Quran 76: 4]
Allah also says (what means): "…Indeed, We have prepared for the wrongdoers a fire whose walls will surround them. And if they call for relief, they will be relieved with water like murky oil, which scalds [their] faces. Wretched is the drink, and evil is the resting place."[Quran 18: 29]
Allah also says (what means): "And those who disbelieved will be driven to Hell in groups until, when they reach it, its gates are opened and its keepers will say: 'Did there not come to you messengers from yourselves, reciting to you the verses of your Lord and warning you of the meeting of this Day of yours?' They will say: 'Yes, but the word [i.e. decree] of punishment has come into effect upon the disbelievers.'"[Quran 39: 71]
Allah also says (what means): "And for those who disbelieved in their Lord is the punishment of Hell, and wretched is the destination. When they are thrown into it, they hear from it a [dreadful] inhaling while it boils up. It almost bursts with rage. Every time a company is thrown into it, its keepers ask them: ‘Did there not come to you a warner?'"[Quran 67: 6-8]
Directions from which punishment comes: In the Hellfire, punishment will be from all directions; Allah says (what means): "On the Day the punishment will cover them from above them and from below their feet and it is said, 'Taste [the result of] what you used to do.'"[Quran 29: 55]
Allah also says (what means):“in scorching fire and scalding water. And a shade of black smoke; Neither cool nor beneficial."[Quran 56: 41-44]
Forms of punishment: One form of punishment in the Hellfire is that people will be dragged on their faces in it, as Allah says (what means): "Indeed, the criminals are in error and madness. The Day they are dragged into the Fire on their faces [it will be said], 'Taste the touch of Saqar (i.e., Hell).'"[Quran 54: 47-48]
Its fuel: People are the fuel by which the Hellfire is heated and flamed; Allah says (what means): "O you who have believed, protect yourselves and your families from a Fire whose fuel is people and stones, over which are [appointed] angels, harsh and severe; they do not disobey Allah in what He commands them but do what they are commanded."[Quran 66: 6]
Allah also says (what means): "Indeed, it throws sparks [as huge] as a fortress, As if they were yellowish [black] camels"[Quran 77: 32-33]
People’s clothes therein: In the Hellfire, people’s clothes will be made of fire; Allah says (what means): "And you will see the criminals that Day bound together in shackles. Their garments of liquid pitch and their faces covered by the Fire."[Quran 14: 49-50]
People’s drink and food therein: Regarding people’s drink and food in Hell,Allah says (what means): "Then indeed you, O those astray [who are] deniers, Will be eating from trees of Zaqqoom. And filling with it your bellies. And drinking on top of it from scalding water. And will drink as the drinking of thirsty camels. That is their accommodation on the Day of Recompense."[Quran 56: 51-56]
Allah also says (what means): "…And he will be given a drink of purulent water. He will gulp it but will hardly [be able to] swallow it. And death will come to him from everywhere, but he is not to die. And before him is a massive punishment."[Quran 14: 16-17]
The duration of punishment: The punishment in the Hellfire is continuous; Allah says (what means): "Indeed, those who disbelieve in Our verses — We will drive them into a fire. 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 4: 56]
Allah also says (what means): “Indeed, the criminals will be in the punishment of Hell, abiding eternally. It will not be allowed to subside for them, and they, therein, are in despair. And We did not wrong them, but it was they who were the wrongdoers.”[Quran 43: 74-76]
The punishment of Hell will be so sever that people will ask to be put to death so they can rest and escape from this punishment, but never will they die, and they will abide in this painful chastisement forever. Allah says (what means): "And they will call, 'O Maalik! Let your Lord put an end to us!' He will say, 'Indeed, you will remain'".[Quran 43: 77]
Allah also says (what means): "And for those who disbelieve will be the fire of Hell. (Death) is not decreed for them, so they may die, nor will its torment be lightened for them. Thus do We recompense every ungrateful one."[Quran 35: 36]
They will ask for the punishment and torment to be lightened, even if it were for one day, so that they can rest. But they will not be responded to and the torment will not be lightened. Allah says (what means): "And those in the Fire will say to the keepers of Hell, 'Supplicate your Lord to lighten for us a day from the punishment.' They will say, 'Did there not come to you your messengers with clear proofs?' They will say, 'Yes.' They will reply, 'Then supplicate (yourselves), but the supplication of the disbelievers is not except in error (i.e. futility)."[Quran 40: 49-50]
One should reflect and see how to escape such a terrifying abode?
