Sahih al-Bukhari Book 78, Hadith 62
A man asked permission to enter upon the Prophet. When the Prophet (ﷺ) saw
him, he said, "What an evil brother of his tribe! And what an evil son
of his tribe!" When that man sat down, the Prophet (ﷺ) behaved with him in
a nice and polite manner and was completely at ease with him. When
that person had left, 'Aisha said (to the Prophet). "O Allah's
Apostle! When you saw that man, you said so-and-so about him, then you
showed him a kind and polite behavior, and you enjoyed his company?"
Allah's Messenger (ﷺ) said, "O 'Aisha! Have you ever seen me speaking a bad
and dirty language? (Remember that) the worst people in Allah's sight
on the Day of Resurrection will be those whom the people leave
(undisturbed) to be away from their evil (deeds)."
The Prophet (ﷺ) was not one who would abuse (others) or say obscene words, or curse (others), and if he wanted to admonish anyone of us, he used to say: "What is wrong with him, his forehead be dusted!"
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."
