Abu Dawud Book 36, Hadith Number 4774.

Narated By ‘Aisha, Ummul Mu’minin : A man asked permission to see the Prophet (PBUH), and the Prophet (PBUH) said: He is a bad member of the tribe. When he entered, the Apostle of Allah (PBUH) treated in a frank and friendly way and spoke to him. When he departed, I said: Apostle of Allah! When he asked permission, you said: He is a bad member of the tribe, but when he entered, you treated him in a frank and friendly way. The Apostle of Allah replied: ‘Aisha! Allah does not like the one who is unseemly and lewd in his language.
