Presence. The Friday Sufi communal gathering for dhikr (prayer of remembrance) and its associated liturgical rituals, prayers, and song recitals, whether private or public; in earlier orders, the “presence” referred to was that of God, but since the eighteenth century it has been considered the spiritual presence of Muhammad . Typically begins with a reading of the office of order and prayers, followed by dhikr and its rituals. Also celebrated on special Islamic festivals and at rites of passage. May be held at home, in a mosque, in a Sufi hospice, or elsewhere.
