Hadra

Haḍra (Arabic: حضرة‎) is a collective supererogatory ritual performed by Sufi orders. It is often held on Thursday evenings after the night prayer, on Fridays after Jum`a prayer or on Sunday evenings, and can also celebrated on special Islamic festivals and at rites of passage. It may be held at home, in a mosque, in a Sufi hospice or elsewhere. The term in Arabic literally means "presence".
