General Behavior (Kitab Al-Adab)
Dawud :: Book 41 : Hadith 4906
Narrated Abdullah ibn Umar:
Nafi' said: Ibn Umar heard a pipe, put his fingers in his ears and went away from the road. He said to me: Are you hearing anything? I said: No. He said: He then took his fingers out of his ears and said: I was with the Prophet (peace_be_upon_him), and he heard like this and he did like this. AbuAli al-Lu'lu said: I heard AbuDawud say: This is a rejected tradition.
