[Koran 3:131] And guard yourselves against the fire which has been prepared for the unbelievers.
[4:56] 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.
[7:50] And the inmates of the fire shall call out to the dwellers of the garden, saying: Pour on us some water or of that which Allah has given you. They shall say: Surely Allah has prohibited them both to the unbelievers.
[8:14] This– taste it, and (know) that for the unbelievers is the chastisement of fire.
[9:68] Allah has promised the hypocritical men and the hypocritical women and the unbelievers the fire of hell to abide therein; it is enough for them; and Allah has cursed them and they shall have lasting punishment.
[9:73] O Prophet! strive hard against the unbelievers and the hypocrites and be unyielding to them; and their abode is hell, and evil is the destination.
[13:35] A likeness of the garden which the righteous are promised; there now beneath it rivers, its food and shades are perpetual; this is the requital of those who guarded (against evil), and the requital of the unbelievers is the fire.
[14:49-50] And you will see the Mujrimun (criminals, disbelievers in the Oneness of Allah, polytheists, disobedient to Allah, etc.) that Day bound together in fetters,
Their garments will be of pitch, and fire will cover their faces.
[18:102] What! do then those who disbelieve think that they can take My servants to be guardians besides Me? Surely We have prepared hell for the entertainment of the unbelievers.
[22:19-22] These are two adversaries who have disputed over their Lord. But those who disbelieved will have cut out for them garments of fire. Poured upon their heads will be scalding water
By which is melted that within their bellies and [their] skins.
And for [striking] them are maces of iron.
Every time they want to get out of Hellfire from anguish, they will be returned to it, and [it will be said], “Taste the punishment of the Burning Fire!”
[76:4] Surely We have prepared for the unbelievers chains and shackles and a burning fire.
[98:6] Indeed, they who disbelieved among the People of the Scripture and the polytheists will be in the fire of Hell, abiding eternally therein. Those are the worst of creatures.
