Abu Dharr reported:
The Mu'adhdbin (the announcer of the hour of prayer) of the Messenger of Allah ( صلی اللہ علیہ وسلم ) called for the noon prayer. Upon this the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: Let it cool down, let it cool down, or he said: Wait, wait for the intensity of heat is from the exhalation of Hell. When the heat is intense, delay the prayer till it becomes cooler. Abu Dharr said: (We waited) till we saw the shadow of the mounds.
