Abu Moosaa al-Ash’aree reported:
Indeed, the people of the Fire [of Hell] shall be weeping in the Fire [of Hell, so much so] that if ships were set to sail upon their tears, they would sail. And after their tears [have dried up from their eyes], they shall shed tears of blood. So because of what they used to do, the weepers shall weep.
