Wahb al-Khuza'i reported: I prayed behind the Messenger of Allah (ﷺ) 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 bin Wahb al-Khuza'i is the brother of 'Ubaidullah bin 'Umar son of Khattab from the side of mother.)
