" 'I BELIEVE IN ONE GOD, AND MAHOMET, AN APOSTLE OF GOD' is the simple and invariable profession of Islam.  The intellectual image of the Deity has never been degraded by any visible idol; the honor of the Prophet has never transgressed the measure of human virtues; and his living precepts have restrained the gratitude of his disciples within the bounds of reason and religion."

EDWARD GIBBON and SIMON OCKLEY speaking on the profession of Islam -- "HISTORY OF THE SARACEN EMPIRES",  London, 1870, p. 54.
