​ISLAM, an Arabic word meaning “pious submission to the will of God,” the name of the religion of the orthodox Mahommedans, and hence used, generically, for the whole body of Mahommedan peoples. Salama, from which the word is derived appears in salaam, “peace be with you,” the greeting of the East, and in Moslem, and means to be “free” or “secure.” (See Mahommedan Religion, &c.)
