Surah 18

Surah 18:29

"Say: ‘The truth is from your Lord. Whoever pleases, let him believe, and whoever pleases, let him disbelieve.’ Surely We have prepared a Fire for the evildoers – its walls will encompass them. If they call for help, they will be helped with water like molten metal (which) will scald their faces. Evil is the drink and evil the resting place!"

The Quran gives graphic descriptions of its concept of hell, as well as its concept of heaven (“Gardens of Eden,” v. 31).
