Sahih Muslim | Book 30 | Hadith Number 5716

Narrated by Anas
Anas reported that there was consternation in Medina. The Messenger of Allah (may peace be upon him) borrowed the horse from Abu Talha which was called Mandub. He rode it and said: We have found no reason for consternation, and we have found it to be (as quick as a torrent) of water.
