Arafat, ah rah faht', or Jebel Errahm (mountain of mercy), a granite hill in Arabia, 15 mi. s. e. of Mecca. It is about 200 feet high and has stone steps reaching to the summit. It is one of the principal objects of pilgrimage among Mohammedans, who say that it was the place where Adam first received his wife, Eve, after they had been expelled from Paradise and separated from each other 120 years. A sermon delivered on the mount constitutes the main ceremony of the Hadj, or pilgrimage to Mecca, and entitles the hearer to the name and privileges of a Hadji, or pilgrim.
