HADJI, an Arabic word signifying pilgrim, hadj being the term used by Mohammedans for the sacred pilgrimage to Mecca. A certain part of the ceremony which takes place at Mecca on the arrival of the pilgrims is also called hadj. The Mohammedan theologians define the original meaning of hadj to be "aspira- tion," and they consider it expressive of the sentiment that man is but a wayfarer on earth travelling toward another and a better world.
