Musnad Ahmad 21533

Translation

✧ The muezzin of the Messenger of God ﷺ called the call to prayer for Zuhr. The Prophet ﷺ said: Delay, delay, or he said: Wait, wait. And he said: The intensity of heat is from the blast of Hell, so when the heat becomes intense, delay the prayer until it cools. Abu Dharr said: Until we saw the shadow of the hillocks.
