(CNN) -- [Updated 3 p.m. Monday, November 7] Thousands of Muslims gather in Mina, near the holy city of Mecca, to take part in one of the final rituals of the Hajj pilgrimage.
In the Jamarat ritual, pilgrims throw pebbles at stone pillars that symbolize Satan. According to Muslim traditions, it is a re-enactment of when Abraham stoned the devil and rejected his temptations.
Every Muslim is expected to make the Hajj pilgrimage at least once in their lives if they are healthy and can afford to. A full explanation of the Hajj can be seen in this video.
