Returning the two testimonies in the adhan and people’s denial of it

Question:
In the name of Allah, the Most Gracious, the Most Merciful. Honorable Shaykh, when you mention that people do the hadith of Abu Muhammad and the people of the famous schools regarding returning the two testimonies, and that this is a recommended practice, they object to you by saying that they have not heard of this from you, and that they have not heard this adhan in the Sacred Mosque or anywhere else, as is their response to you.

Answer:
He does not hear the returning, may Allah correct you. The returning is not heard; he says it to himself. The mu'adhdhin says it to himself; it is not heard. He says it to himself in secret. He recites the two testimonies in secret, and that is not heard from him. Then he raises his voice with it. Also, do not say it to the people so as to disturb them. If you are the mu'adhdhin some of the times and you did it, there is no harm. But that you order the people to do it, no. I mean, this disturbs them, as you mentioned.
