Ten years after the migration, the Messenger of Allah ordered to his close followers to call all the people in different places to join him in his last pilgrimage. On this pilgrimage he taught them how to perform the pilgrimage in a correct and unified form. This was first time that the Muslims with this magnitude gathered in one place in the presence of their leader, the Messenger of Allah. On his way to Mecca, more than seventy thousand people followed Prophet (S). On the fourth day of Dhul-Hajjah more than one hundred thousand Muslims had entered Mecca.
