Muslim pilgrims pray at the Grand Mosque in Mecca January 17, 2005. About two million Muslim pilgrims gathered for their haj pilgrimage this year. The Haj is one of a Muslim's duties, as described in the five pillars of Islam, to go on a haj at least once during his or her lifetime, if affordable. Prophet Muhammad had said that a person who performs haj properly will return as a newly born baby, free of all sins. NO RIGHTS CLEARANCES OR PERMISSIONS ARE REQUIRED FOR THIS IMAGE.
