The mountain associated with the plain where pilgrims stand during the Day of Arafah is Mount Arafat. It is also called Jabal al-Rahmah, meaning “Mountain of Mercy.”
Mount Arafat is a granite hill in the Arafat plain east of Mecca. On 9 Dhu al-Hijjah, pilgrims performing Hajj gather in the surrounding area for wuquf, the standing rite that is considered essential to the pilgrimage. The sermon and prayers at Arafat form a major part of the Hajj experience.
The hill itself is not the only valid location for the rite; the wider plain of Arafat is the relevant sacred area. Mount Arafat is therefore different from Mount Hira, the cave-bearing mountain associated with the first Quranic revelation, and Mount Uhud, a mountain near Medina linked to the Battle of Uhud.
