Chapter: It is recommended to pray Zuhr at the beginning of its time when there is no intense heat
Hammam b. Munabbih reported: This is what Abu Huraira narrated to us from the Prophet and he transmitted some ahadith-one of them was that the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: Let the heat become less severe before prayer, for the intensity of heat is from the exhalation of Hell.
