MINA, Saudi Arabia: Millions of Muslim pilgrims were pelting stone walls representing the devil before a final trip back to Islam s holiest site on the closing day of the annual Hajj. Around 3 million pilgrims were casting pebbles Sunday at three walls in the desert valley of Mina in a symbolic rejection of Satan s temptation for a third consecutive day. The faithful were then scheduled head back to Mecca for a final journey - known as the Farewell Circulation - around the Kaaba, Islam s most sacred site. The Islamic pilgrimage is the largest yearly gathering of people in the world. The Muslims believe that they are cleared of all sins if they perform a sincere pilgrimage. -AP
