What did the Prophet Muhammad (peace be upon him) do when he lead prayers at the occasion of the Farewell Pilgrimage?
 Wahb al-Khuza'i reported:                      I prayed behind the Messenger of Allah (way peace be upon him) at Mina, and there was the greatest number of people, and they prayed two rak'ahs on the occasion of the Farwell Pilgrmage. (Muslim said: Haritha b. Wahb al-Khuza'i is the brother of 'Ubaidullah b. 'Umar son of Khattab from the side of mother.)
