Surah 78. An-Naba, Ayah 26

Their transgressions go on progressively as they refuse to repent and turn to Allah. The fire of misery begins to blaze forth more and more fiercely, an there is nothing to cool that blaze; their food and drink themselves are tainted with the disorder of contradictory elements,-boiling hot drink, with intensely cold, murky, and disgusting fluids. These are fitting punishments for their crimes, which are inconsistent with the pure and gentle mould in which Allah had originally cast their nature.
