The severity of its heat, and their variation in it: An-Nu`man ibn Bashir, radhiallahu `anhu, narrated that he heard the Prophet, sallallahu `alaihi wa sallam say:

“The least torture in the Hell on the Day of Judgment is that of a man whose foot sole is laid on a live coal which causes his brain to boil just like a boiler.” [Bukhari and Muslim]

Muslim narrated in his Sahih:

“He does not think that any other person is tortured more severely than him although he is in the least torture.” [Muslim]

Abu Huraira, radhiallahu `anhu, narrated:

This fire of yours which burns the son of Adam (in this world) is the seventieth part of the heat of the Hell. They say: ‘We swear by Allah, our fire is quite enough.’ The Prophet said: ‘It is sixty nine times more and each part of it is like the heat of your fire.’” [Muslim]

Abu Huraira said that the Prophet sallallahu `alaihi wa sallam said:

“The Hell complained to her Rabb: O my Rabb! I am eating myself. He allowed her two breaths: One in winter and the other one in summer, and that is why you feel the heat in Summer and the cold in Winter.” (Bukhari and Muslim)

Samura narrated that he heard the Prophet, sallallahu `alaihi wa sallam, said:

Fire holds some to their ankle bones, some to their knees, some to their waists, and some up to their collarbones.” [Muslim]

This Hadith is a statement for the variation in degrees in the punishment of those in the Hell. We seek protection of Allah from it and from anything that leads to it whether word or deed.
