It is narrated from Hazrat Ata bin Yasar that the Messenger of Allah, peace and blessings be upon him, said: "Intense heat is from the boiling of Hell, so when the heat is severe, delay the prayer until it cools down." And the Prophet, peace and blessings be upon him, said: "The Fire complained to its Lord and said: O my Lord! I am consuming myself. So its Lord permitted it two breaths every year: a breath inward in winter and a breath outward in summer."
