Abu Dawud Book 36, Hadith Number 4906.

Narated By 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 (PBUH), and he heard like this and he did like this. AbuAli al-Lu’lu said: I heard AbuDawud say: This is a rejected tradition.
