General Behavior (Kitab Al-Adab)
Dawud :: Book 41 : Hadith 4770
Narrated Aisha, Ummul Mu'minin:
When the Prophet (peace_be_upon_him) was informed of anything of a certain man, he would not say: What is the matter with so and so that he says? But he would say: What is the matter with the people that they say such and such?
