In the hadith (And appoint a mu'adhdhin who does not take a wage for his adhan), does this indicate that it is not permissible to take a wage for the adhan?

Question:
Honorable Shaykh, may Allah grant you success. The questioner says: In the saying of the Messenger (peace and blessings be upon him) , does that imply that it is not permissible to take a wage for the adhan?

Answer:
A specific wage is not permissible, just as with other works. I do not build you a house or a wall except for a wage, and I do not give the adhan for you except for a wage; it is not permissible. As for a wage from the public treasury, that is not a wage; it is a provision from the public treasury. The imams and the mu'adhdhins have a right to the public treasury, so there is no harm in that. Yes.
