"They will have from Hellfire a bed and over them from it coverings. Thus do We reward the unjust."
[al-Araf, 7: 41]
"It may be that your Lord may show mercy unto you, but if you revert to your sins. We will revert to Our punishments. And We have made Hell a mat for the disbelievers."
[al Isra', 17: 8]
