John H. Haaren, Famous Men of the Middle Ages… (1904)
“ The tomb of Mohammed is visited every year by people from all Mohammedan countries. Mecca, the birthplace of the prophet, is also visited by vast numbers of pilgrims. Every Mussulman is bound by his religion to make a visit or pilgrimage to Mecca at least once in his life. Whenever a Mussulman prays, no matter in what part of the world he may be, he turns his face towards Mecca, as if he were always thinking of going there. ”
