Ihram denotes the state of consecration which is essentiallyrequired for performing Hajj and 'Umrah. The outward garb which consists in the case of men of just two sheets of cloth instead of tailored clothes is one of the conditions of ihram but not identical with it. Apart from donning that garb, one is required to pronounce talbiyah (Labbayk Allahumma Labbayk...). In the state of ihram the pilgrim is required to observe many prohibitions; e.g. he may not hunt, shave or trim his hair, shed blood, use perfume, or indulge in sexual gratification.
