"The companions of the left hand - what are the companions of the left hand? (They will be) in the midst of a fierce blast (of fire) and in boiling water and in the shades of black smoke - nothing cool and nothing beneficial."
[Waqi'ah, 56: 41-44]
"And woe that Day to the deniers (of truth). ([It will be said], 'Depart to a shadow [of smoke ascending] in three columns, [which yields] no shade of coolness and is of no use against the fierce blaze.'"
[Mursalat, 77: 28-31]
