On the second day of the Hajj, pilgrims arrive at Mt. Arafat, where they spend the day in prayer. The time spent here is most important part of the pilgrimage, and without it, a person’s pilgrimage is not considered complete. Mt. Arafat is the spot where Mohammed is believed to have made his final sermon. The pilgrims remain there until sunset.
At sunset, they set out on foot again, this time to Muzdalifah, where they spend the night and may begin collecting pebbles needed for the next day’s rituals.
