Narrated by 'Abdullah bin 'Abbas
That he came riding a donkey when Allah 's Apostle was standing at Mina during Hajjat- ul-Wada', leading the people in prayer. The donkey passed in front of a part of the row (of

the people offering the prayer). Then he dismounted from it and took his position in the row with the people.
