I was sitting behind Ibn ‘Umar on the mount when he passed a shepherd who was blowing a pipe. He then mentioned the rest of the tradition in a similar manner.

Abu Dawud said : Between Mut’im and Nafi the name of a narrator Sulaiman b. Musa has been inserted.

← Previous Hadith 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 (ﷺ), and he heard like this and he did like this.

AbuAli al-Lu'lu said: I heard AbuDawud say: This is a rejected tradition.
