What is a Muslim church called?

A Muslim "church" is normally called in English a "mosque". It is the anglicized form of the Arabic term "masjid", which literally means "place of prostration" and a term used by Muslims just as the Jews use the term "temple" or "synagogue" and Christians use the term "church". Primarily "masjid" is used in the Quran, i.e. Islamic scripture, to mean any place of worship dedicated to God including churches, temples and synagogues.
