Mu'adhdhin is an Arabic term that refers to a person who calls for prayer. In some cultures, this person is also known as a muezzin. In English, there are several synonyms that can be used to describe a mu'adhdhin, such as a prayer caller, a mosque announcer, or a caller to the faithful. Other synonyms can include adhan caller, muazzin, and salaat coordinator. Regardless of the term used, the role of the mu'adhdhin remains crucial in ensuring that Muslims are reminded of the importance of prayers and are motivated to take part in them regularly.
