We were in the company of the Prophet (ﷺ) on a journey and the Mu'adh-dhin wanted to pronounce theAdhan for the (Zuhr) prayer. The Prophet (ﷺ) said to him, "Let it become cooler." Then he again wantedto pronounce the Adhan but the Prophet; said to him, "Let it become cooler." The Mu'adh-dhin againwanted to pronounce the Adhan for the prayer but the Prophet (ﷺ) said, "Let it become cooler," till theshadows of the hillocks become equal to their sizes. The Prophet (ﷺ) added, "The severity of the heat isfrom the raging of Hell."
