Imam Bukhari narrates: Muslim bin Ibrahim narrated to us, he said: Shu'bah narrated to us from al-Muhajir bin Abi al-Hasan from Zaid bin Wahb from Abu Dharr, may Allāh be pleased with him, he said:
We were with the Prophet ﷺ on a journey, so the mu'adhdhin intended to give the Adhan, then he said to him: Give the Adhan when it is cool. He intended to give the Adhan again, then he said to him: Give the Adhan when it is cool. He intended to give the Adhan again, then he said to him: Give the Adhan when it is cool, until the shadow became equal to the mounds. Then the Prophet ﷺ said: The intensity of heat is from the raging of Hell.
