When Mohammed had fully established his new religion he turned out all the old deities except the Black Stone, which he himself worshipped, and concerning which worship he left minute directions for his followers. Such was the inconsistency of the prophet whose creed was “There is no god but Allah.” The object of the pilgrimage as instituted by Mohammed was to worship the Sacred Mosque and Kaaba. According to Moslem writers, the Kaaba was built by Adam, exactly under the spot occupied by God’s throne in heaven. It is an oblong building in the centre of the mosque, covered with a black cloth, and in it is the sacred Black Stone which came down from heaven snow-white, and was turned black by the sins of the people. The Black Stone is located on the southeast corner of the Kaaba, about five feet from the ground. It is probably an aerolite, black and sprinkled with lighter patches and came down as a falling star. Many years after Mohammed’s death it was stolen by some of the Arabs on the Persian Gulf and carried across the desert to Katif; when it was carried back again it fell from the camel on its long journey and was broken. Now a silver band holds the pieces together and the whole stone is imbedded in the wall. [Illustration: The Black Stone at Mecca] It is necessary for every Moslem to visit Mecca at least once during his lifetime. When all these pilgrims arrive within a short distance of the Holy City, they must put off their every-day clothing and put on the pilgrim garb, which consists of two pieces of white cloth,—one tied around the loins and the other drawn over the shoulders, under their arm, leaving one shoulder bare. The pilgrims are allowed to wear sandals, but not shoes. Thus clad every one goes in turn to the sacred well of Zem Zem, washes his whole body with a pailful of the water, and then drinks as much as he cares. Then he enters the “door of peace” and kisses the most wonderful stone in the world, running around the Kaaba seven times and each time when he passes the stone he strokes it with his hand or kisses it. After this all the Moslem pilgrims say the regular prayer and retire.
