Al-Ghazali on the Shame of Hell

"Suppose a certain king had been celebrating his son's marriage. In the evening the young man goes off with some companions and presently returns to the palace (as he thinks) intoxicated. He enters a chamber where a light is burning and lies down, as he supposes, by his bride. In the morning, when soberness returns, he is aghast to find himself in a mortuary of fire-worshipers [by which he means Zoroastrians], his couch a bier, and the form which he mistook for that of his bride the corpse of an old woman beginning to decay. On emerging from the mortuary with his garments all soiled, what is his shame to see his father, the king, approaching a retinue of soldiers! Such is a feeble picture of the shame those will feel in the next world who in this have greedily abandoned themselves to what they thought were delights."

--Abu Hamid al-Ghazali, The Alchemy of Happiness, ch. 4
