‘Abd al-‘AzIz b. Rufai' said he asked Anas b. Malik to tell him something he knew about God's messenger, viz. where he prayed the noon prayer on yaum at-tarwiya, and he replied that it was in Mina. He asked where he had prayed the afternoon prayer on yaum an-nafr,(There are two days with this name, the first being the 12th of Dhul Hijja and the second the following day. The second of these is said to be the one referred to here) and he replied that it was in al-Abtah.(The part of the wadi of Mecca with small pebbles) He then said,“Do as your commanders do.”Bukhari and Muslim.
