"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]
"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]
"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]
"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]
