"There was a cause of fright in Al-Madinah. So the Messenger of Allah (ﷺ) borrowed a horse of ours called Mandub. He said: 'I have not seen anything to be frightened of, and we found him to be (quick) like the sea.'" This Hadith is Hasan Sahih.

That the Prophet (ﷺ) said: "No stake is acceptable except in archery, racing a camel, and racing a horse."
