Abu Dharr reported,

We were with the Prophet ﷺ on a journey when the muezzin wanted to call the adhan. The Prophet ﷺ said to him, "Wait until it cools down."Then he wanted to call the adhan again, and the Prophet ﷺ said, "Wait until it cools down."Then he wanted to call the adhan once more, and the Prophet ﷺ said, "Wait until it cools down," until the shadows became level with the mounds.Then the Prophet ﷺ said, "The intensity of heat is from the raging of Hellfire."

كنا مع النبي ﷺ في سفر فأراد المؤذن أن يؤذن فقال له أبرد ثم أراد أن يؤذن فقال له أبرد ثم أراد أن يؤذن فقال له أبرد حتى ساوى الظل التلول فقال النبي ﷺ إن شدة الحر من فيح جهنم
