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.
People are the fuel by which the Hellfire is heated and flamed; Allah says:
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(interpretation of the meaning)
Allah also says:
Indeed, it throws sparks [as huge] as a fortress, as if they were yellowish [black] camels.
Quran - 77:32-33(interpretation of the meaning)
The punishment in the Hellfire is continuous; Allah says:
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(interpretation of the meaning)
Regarding people's drink and food in Hell, Allah says:
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(interpretation of the meaning)
Finally, the punishment of the Hellfire is never reduced, nor will its dwellers ever die, as Allah says:
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. And they will call, ‘O Malik, let your Lord put an end to us!’ He will say, ‘Indeed, you will remain.’
Quran - 43:74-77(interpretation of the meaning)
