Arafat, Or Orphat (Arabic, gratitude), a granitic hill in Arabia, near Mecca, a pilgrimage to which is enjoined upon all who visit that city. It rises about 200 feet above the plain. The pilgrimage occupies three days from Mecca. On the second day the ceremony of the sermon on the mount is observed. The cadi of Mecca usually preaches the sermon, riding first upon a camel up the entire length of the stone steps which ascend the mountain to the summit. Hearing this sermon is the great point of the pilgrimage, and confers the title of hadji (pilgrim). There is a tradition among the Mohammedans that on this mountain Adam first met Eve again, after a separation of 120 years immediately following the expulsion from paradise. On the summit is a chapel, which, according to tradition, was built by Adam himself.
