أين توجد جهنم، ومن هم حراسها في القرآن أو السنة؟

Fire exists now, and Allah has prepared it for the disbelievers. Paradise exists now, and Allah has prepared it for the righteous. The texts are continuously transmitted regarding their existence, and no explicit text has been reported specifying their location. The majority opinion is that Paradise is above the seven heavens and beneath the Throne, and that Fire is beneath the seven earths.

The custodians of Hell are the noble angels. Allah Almighty has specifically assigned nineteen angels to it, headed by Malik, the keeper of the Fire.
