Narrated Abu Mandhura (RA):

The Prophet (ﷺ) liked his voice, so he taught him the Adhan (call to prayer). [Reported by Ibn Khuzaimah].

وَعَنْ أَبِي مَحْذُورَةَ ‏- رضى الله عنه ‏- { أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-أَعْجَبَهُ صَوْتُهُ, فَعَلَّمَهُ اَلْآذَانَ } رَوَاهُ اِبْنُ خُزَيْمَةَ [1]‏ .‏
