Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: My brother Fadl and I came riding on a donkey, and the Noble Prophet (peace and blessings be upon him) was leading the prayer at Mina or Arafat. I passed through the middle of the row, got down from the donkey, left it to graze, and joined the row. (In the narration of Bukhari: No one objected to me for this.)
