question #2 Sahih Muslim 615e, Book 5, Hadith 233 : What is the significance of associating intense heat with the exhalation of Hell in Islamic tradition?

This is what Abu Huraira narrated to us from the Prophet and he transmitted some ahadith-one of them was that the Messenger of Allah (ﷺ) said: Let the heat become less severe before prayer, for the intensity of heat is from the exhalation of Hell.
