The Arabic for ordinary bathing is غسلghasl, and that br the religious purification of the whole body ghusl. In all large mosques, and in most respectable dwellings in Muslim countries, there are bathing rooms erected, both for the ordinary purposes of bathing and for the religious purification. An account of the legal purification will be found in the article GHUSL. Although purifications and bathing form so essential a part of the Muslim religion, cleanliness does not distinguish Muslims, who are generally in this respect a striking contrast to their Hindu fellow subjects in India. According the saying of Muhammad, decency should he observed in bathing, and the clothes from the waist downwards should not be taken off at such times. (Mishkat, ii. c. iv.)
