Hell Breathes

Bukhari: Volume 4, Book 54, Number 482:

Narrated Abu Huraira: Allah's Apostle said,

"The (Hell) Fire complained to its Lord saying, 'O my Lord! My different parts eat up each other.' So, He allowed it to take two breaths, one in the winter and the other in summer, and this is the reason for the severe heat and the bitter cold you find (in weather)."
