General Behavior (Kitab Al-Adab)
Dawud :: Book 41 : Hadith 4776
Narrated Anas ibn Malik:
I never said that when any man brought his mouth to the ear of the Apostle of Allah (peace_be_upon_him) and he withdrew his head until the man himself withdrew his head, and I never saw that when any man took him by his hand and he withdrew his hand, until the man himself withdrew his hand.
