He also reported from Abu Hurairah (RA):

The Prophet (ﷺ) said: "No one should announce Adhan except the one who has performed the ablution". [Reported by at-Tirmidhi who graded it Da'if (weak)]. So the narration is weak whether Marfu' [reaching back to the Prophet (ﷺ)] or Mawquf (saying of a Companion).

وَلَهُ : عَنْ أَبِي هُرَيْرَةَ ‏- رضى الله عنه ‏- أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-قَالَ : { لَا يُؤَذِّنُ إِلَّا مُتَوَضِّئٌ } وَضَعَّفَهُ أَيْضًا [1]‏ .‏ فَالْحَدِيثُ ضَعِيفٌ مَرْفُوعًا وَمَوْقُوفًا .‏
