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 companions (sahaba) 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 (Hawa) 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.
