Narrated Aisha: A man asked permission to see the Prophet. He said, "Let Him come in; What an evil man of the tribe he is! (Or, What an evil brother of the tribe he is). But when he entered, the Prophet spoke to him gently in a polite manner. I said to him, "O Allah's Apostle! You have said what you have said, then you spoke to him in a very gentle and polite manner? The Prophet said, "The worse people, in the sight of Allah are those whom the people leave (undisturbed) to save themselves from their dirty language."

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 Apostle 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)."
