Which Arab leader assumed the name of a peak visited during the Haj as his suranme?

Yasir Arafat,who was Chairman of the Palestine Liberation Organization (PLO; 1969–2004) and President of the Palestinian National Authority....however there is an uncertainity,because there is no reference anywhere that he changed his surname...he was named "Mohammed Abdel-Raouf Arafat al-Qudwa al-Husseini"... (reason:Mount Arafat or Mount Arafah (Arabic: جبل عرفات; transliterated Jabal 'Arafat) is a granite hill east of Mecca. It is also known as the Mountain of Mercy (Jabal ar-Rahmah). The hill is the place Muhammad 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)
