Sahih Muslim | Book 30 | Chapter 11
Narrated by Anas b. Malik
Anas b. Malik reported that Allah's Messenger (may peace be upon him) was the sublimest among people (in character) and the most generous amongst them and he was the bravest of men. One night the people of Medina felt disturbed and set forth in the direction of a sound when Allah's Messenger (may peace be upon him) met them on his way back as he had gone towards that sound ahead of them. He was on the horse of Abu Talha which had no saddle over it, and a sword was slung round his neck, and he was saying: There was nothing to be afraid of, and he also said: We found it (this horse) like a torrent of water (indicating its swift-footedness), whereas the horse had been slow before that time.
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.
