Is it permissible to ask the mu'adhdhin of one mosque to move to another mosque?

Question:
May Allah reward you. Honorable Shaykh, among the questions that came to the program, one says: I am the imam of a mosque that did not have a mu'adhdhin, so I contacted the mu'adhdhin of another mosque to come to my mosque because of the advantages it offers him, and this is better than the mosque where he currently calls to prayer. Is this valid? Or is this considered analogous to selling on top of one's brother's sale, making it forbidden?

Answer:
No, this is not a sale. If he has the desire to move, offer it to him. Moving from one mosque to another is permissible, so offer it to him, and the other mosque will find a mu'adhdhin for themselves.
