Abu Hurairah reported,

The Prophet ﷺ said, "The Fire complained to its Lord, saying, 'My Lord, one part of me has devoured another.' So He permitted it two breaths, one breath in winter and one breath in summer. That is the most intense heat you experience and the most intense bitter cold you experience."

Bukhari 537
