Times of the Prayers
Chapter: In severe heat, offer Zuhr prayers when it becomes (a bit) cooler
Narrated Abu Huraira and `Abdullah bin `Umar:
Allah's Messenger (ﷺ) said, "If it is very hot, then pray the Zuhr prayer when it becomes (a bit) cooler, as the severity of the heat is from the raging of the Hell-fire."
