A journey through Hajj, Islam's special pilgrimage

the 1.8 billion Muslims around the world, the Hajj is considered a spiritual pinnacle. Each year, up to three million pilgrims descend on Mecca -- the epicenter of the Muslim world
All Muslims who are physically and financially able are required to make the journey to Mecca at least once in their lifetime.

Mecca is brimming with over 1.5 million international pilgrims this year, according to Saudi officials. These are devout Muslims who tenaciously pursue the pilgrimage, enduring the inconveniences of an arduous journey and sidestepping hurdles put in place by a difficult political climate whose temperatures continue to climb, and ignoring a string of unbecoming stories about the Hajj, including stampedes, fires and sexual harassment.
They prefer instead to focus on spiritual nourishment that the Hajj promises to supply.
Saudi authorities manage the entry and exit of pilgrims through strict visa applications and have a dedicated Hajj ministry, employing 40,000 workers. In the last 10 years, 24 million Hajj pilgrims have visited the city. Thousands of civil servants are deployed to the pilgrimage each year.
