What is the ruling on the mu'adhdhin who calls the adhan and then leaves the mosque, and then comes back for the iqamah, but sometimes does not come?

Question:
The mu'adhdhin of a mosque says that when he calls the adhan, he leaves the mosque and sits in his house until the time for the iqamah of the prayer comes. Sometimes the imam performs the iqamah on his behalf, and his house is next to the mosque. What is the ruling on this action? Is it permissible for him to do so?

Answer:
The mu'adhdhin must be present in the mosque because he is responsible for the mosque and for the iqamah. The iqamah is part of his duty, as is the protection of the mosque and the supervision of the mosque. So he must be present in the mosque after the adhan; he must be present in the mosque. If a need arises for him, he may go to attend to it and return soon; he returns soon. If he knows that this need is a dire necessity and that it is not possible for him to return soon, he appoints someone to perform the iqamah on his behalf. Yes.
