Volume 1, Book 10, Number 512:
Narrated Abu Huraira:
The Prophet said, "In very hot weather delay the Zuhr prayer till it becomes (a bit) cooler because
the severity of heat is from the raging of Hell-fire. The Hell-fire of Hell complained to its Lord say –
ing: O Lord! My parts are eating (destroying) one another. So Allah allowed it to take two breaths,
one in the winter and the other in the summer. The breath in the summer is at the time when you
feel the severest heat and the breath in the winter is at the time when you feel the severest cold."
