What did the Prophet Muhammad (saw) do upon seeing Ibn 'Abbas come riding on a she-ass while leading people in prayer at Mina?
 Ibn 'Abbas reported:                      I came riding on a she-ass, and I was on the threshold of maturity, and the Messenger of Allah (may peace be upon him) was leading people in prayer at Mina. I passed in front of the row and got down, and sent the she-ass for grazing and joined the row, and nobody made any objection to it.
