Anas told that, once when the people of Medina had an alarm the Prophet mounted a slow horse belonging to Abu Talha which took short steps. When he returned, he said, "I found this horse of yours could run like a great river." After that it had none to compete with it. A version says it was never outstripped after that day. Bukhari transmitted it.
