Mount Arafat and Muzdalifah
Mount Arafat
The next morning, on the ninth of Dhu al-Hijjah, the pilgrims leave Mina for Mount Arafat where they stand in contemplative vigil, near a hill from which Muhammad gave his last sermon. This is considered the highlight of the Hajj. Pilgrims must spend the afternoon within a defined area on the plain of Arafat until after sunset. No specific rituals or prayers are required during the stay at Arafat, although many pilgrims spend time praying, and thinking about the course of their lives. If a pilgrim does not spend the afternoon on Arafat then their pilgrimage is considered invalid.

Muzdalifah
As soon as the sun sets, the pilgrims leave Arafat for Muzdalifah, an area between Arafat and Mina, where 49 pebbles are gathered for the next day's ritual of the stoning of the Devil (Shaitan). Many pilgrims spend the night sleeping on the ground at Muzdalifah before returning to Mina. It is now the 10th of the month, the day of Eid ul-Adha.
