I heard the Messenger of Allah ﷺ say, "The callers to prayer will have the longest necks of all people on the Day of Resurrection."
سمعت رسول الله ﷺ يقول: المؤذنون أطول الناس أعناقا يوم القيامة.
Muslim narrated it in the Book of Prayer (387) through the route of Talha bin Yahya, from his uncle, who said, "I was with Muawiya bin Abu Sufyan when the muezzin came to call him to prayer," and he mentioned the hadith.
