An Islamic teacher is a person who is knowledgeable in the teachings of Islam and is responsible for educating others in the faith. The two most common terms used to refer to an Islamic teacher are MULLAH, which is a term used in some parts of the Muslim world, and Imam, which is a term used in other parts of the Muslim world. Both Mullahs and Imams are expected to be knowledgeable in Islamic law, theology, and religious practices.
