The cancellation of the Hajj pilgrimage sent shock waves of sadness and disappointment across the Muslim world. Performing the pilgrimage at least once for those who are physically and financially able is one of the five pillars of Islam. Making the trip is a sacred milestone for the world’s 1.8 billion Muslims. The Saudi government announced on Monday that no pilgrims from outside the kingdom could perform the hajj this year. On Tuesday, Saudi officials narrowed the order, saying that only about 1,000 pilgrims would be permitted this year, a tiny fraction of the 2.5 million who came last year. The cancellation weighs particularly heavily on older Muslims who have been waiting for years to go in hopes that they can fulfill their religious obligation before death.
