State of ritual consecration to perform major pilgrimage (Hajj) or minor one (ëumrah).
Useful information: Pilgrims who come to Mecca for the hajj from a long distance and want to perform the 'umra before the hajj are allowed to enter into a state of consecration (ihram) for the 'umra and then to leave it until they re-enter it for the hajj. During the intervening period they can 'enjoy themselves' (tamattu') with the activities of everyday life that are forbidden in the state of ihram. This tamattu' before the hajj is known as mut'at al-hajj.
