Sayyiduna Abu Dharr (may Allah be pleased with him) narrates that we were on a journey with the Prophet (peace and blessings of Allah be upon him), and when the mu’adhdhin intended to give the adhan, the Prophet (peace be upon him) said: “Cool it.” Then when he wanted to give the adhan again, the Prophet (peace be upon him) said: “(Let it) cool.” Shu’bah says, until the shadow became equal to the mounds, then the Messenger of Allah (peace be upon him) said: “Indeed, the severity of heat is from the boiling of Hell, so perform (the Zuhr) prayer when it cools down.”
