Rifa'i
Rifai (also Rifaiyya, Rufai or Rufaiyya; Arab الطريقة الرفاعية, DMG aṭ - Tariqa ar Rifa ʿ iya ) is an Islamic Sufi order ( tariqa ), which was founded by the famous Muslim mystic Ahmed Rifai ( 1118-1181 ).
In the West, the Order is due to the ecstatic dhikr also known by the name " the howling dervishes ".
