Mount Arafat or Mount Arafah (Arabic: جبل عرفات transliteratedJabal ‘Arafāt) is a granitehill east of Mecca. It is also known as the Mount of Mercy (Jabal ar-Rahmah). According to Islamic tradition, the hill is the place where the Islamic prophet Muhammad stood and delivered the Farewell Sermon to the Muslims who had accompanied him for the Hajj towards the end of his life. It reaches about 70 m in height.
The pilgrims spend the whole day on Arafah supplicating to Allah to forgive their sins and praying for personal strength in the future. They also collect stones for the stoning of Satan.
The level area surrounding the hill is called the Plain of Arafat. The term Mount Arafat is sometimes applied to this entire area. It is an important place in Islam because during the Hajj, pilgrims spend the afternoon there on the ninth day of Dhul Hijjah (ذو الحجة). Failure to be present in the plain of Arafat on the required day invalidates the pilgrimage. Many pilgrims stay here all night in vigil.
Since late 2010, this place is served by Mecca Metro. On a Normal Hajj the Mount would be around thirteen miles to walk and would be the 3rd day of events after the Pilgrims have drunk from the well of ZamZam.
According to Islam,The People will gather around Mt.Arafat on the Day of Judgement ,he hill is referenced in James Joyce's novel Finnegans Wake.
