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).
