Mishkat al-Masabih #547

Abu Huraira reported God’s Messenger as saying, “When the heat is severe, postpone the prayer till it is cooler.” A version by Bukhari from Abu Sa‘id has, “at noonday, for the violent heat comes from the bubbling over of Jahannam, and hell complained to its Lord saying, ‘My Lord I am being devoured by myself,' so He allowed it two exhalations one in winter and one in summer, the most severe heat and the most severe cold you experience.” (Bukhari and Muslim.) A version by Bukhari has, “The most severe heat you experience comes from its hot wind, and the most severe cold you experience comes from its intense cold.”
