Sahih al-Bukhari Book 78, Hadith 64
Never was the Prophet (ﷺ) asked for a thing to be given for which his answer was 'no'.
The Prophet (ﷺ) was the best among the people (both in shape and character) and was the most generous of them, and was the bravest of them. Once, during the night, the people of Medina got afraid (of a sound). So the people went towards that sound, but the Prophet (ﷺ) having gone to that sound before them, met them while he was saying, "Don't be afraid, don't be afraid." (At that time) he was riding a horse belonging to Abu Talha and it was naked without a saddle, and he was carrying a sword slung at his neck. The Prophet (ﷺ) said, "I found it (the horse) like a sea, or, it is the sea indeed."
We were sitting with `Abdullah bin `Amr who was narrating to us (Hadith): He said, "Allah's Messenger (ﷺ) was neither a Fahish nor a Mutafahhish, and he used to say, 'The best among you are the best in character (having good manners)."'
