Narrated `Aisha:
A man asked permission to enter upon Allah's Messenger. The Prophet (ﷺ) said, "Admit him. What an evil brother of his people or a son of his people." But when the man entered, the Prophet (ﷺ) spoke to him in a very polite manner. (And when that person left) I said, "O Allah's Messenger! You had said what you had said, yet you spoke to him in a very polite manner?" The Prophet (ﷺ) said, "O `Aisha! The worst people are those whom the people desert or leave in order to save themselves from their dirty language or from their transgression."
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 (ﷺ) 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 (ﷺ) said, "The worse people, in the sight of Allah are those whom the people leave (undisturbed) to save themselves from their dirty language."
A'isha reported that a person sought permission from Allah's Messenger (ﷺ) to see him. He said: Grant him permission. (and also added: ) He is a bad son of his tribe or he is a bad person of his tribe. When he came in he used kind words for him. 'A'isha reported that she said: Allah's Messenger, you said about him what you had to say and then you treated him with kindness. He said: A'isha, verily in the eye of Allah, worst amongst the person in rank on the Day of Resurrection is one whom the people abandon or desert out of the fear of indecency.
