I will surely cast him [the unbeliever] into the Fire. Would that you know what the fire is like! It leaves nothing, it spares no one; it burns the skins of men. It is gaurded by 19 keepers.
We have appointed none but angels to gaurd the Fire, and made their number a subject for dispute among the unbelievers, so that those to whom the Scriptures were given may be convinced and the true believers strengthened in their faith.
Quran, sura 74:31
Nothing like Quran reading on this happy Ramadan holiday season, pbuh.
