Narrated Anas:
The Prophet (ﷺ) was the nicest person among the people, the most generous of the people, and the bravest among the people. He said: The inhabitants of Al-Madinah became freightened one night upon hearing a loud noise. He said: So the Prophet (ﷺ) met them upon an unsaddled horse belonging to Abu Talhah, with a sword hanging around his neck. He said: 'I found him to be (quick) like the sea.' - meaning the horse.
[Abu 'Eisa said:] This Hadith is Hasan Sahih.
