Volume 8, Book 73, Number 152:
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 man –
ner? The Prophet said, “The worse people, in the sight of Allah are those whom the people leave (un –
disturbed) to save themselves from their dirty language.”
