Mount Arafat, and by its other Arabic name, Jabal ar-Raḥmah, is a granodiorite hill about 20 km southeast of Mecca, in the province of the same name in Saudi Arabia. The mountain is approximately 70 m in height, with its highest point sitting at an elevation of 454 metres.
According to some Islamic traditions, the hill is the place where the Prophet Muhammad stood and delivered the Farewell Sermon, also known as the Khutbat al-Wada', to his Sahabah who had accompanied him for the Hajj towards the end of his life. Some Muslims also believe that Mount Arafat is the place where Adam and Eve reunited on Earth after falling from Heaven, believing the mountain to be the place where they were forgiven, hence giving it the name Jabal ar-Rahmah, meaning "Mountain of Mercy". A pillar is erected on top of the mountain to show where this event is believed to have taken place.
The mountain is especially important during the Hajj, with the 9th day of the Islamic month of Dhu al-Hijjah, also known as the Day of 'Arafah after the mountain itself, being the day when Hajj pilgrims leave Mina for Arafat; this day is considered to be the most important day of the Hajj.
