In Shia Islam, marjaʿ (Arabic: مرجع‎; plural: marājiʿ), also known as a marjaʿ taqlīd or marjaʿ dīnī (Arabic: مرجع تقليد / مرجع ديني‎), literally meaning "source to imitate/follow" or "religious reference", is a title given to the highest level Shia authority, a Grand Ayatollah with the authority to make legal decisions within the confines of Islamic law for followers and less-credentialed clerics. After the Qur'an and the prophets and imams, marājiʿ are the highest authority on religious laws in Usuli Shia Islam.
