Nafi narrates: Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) heard the sound of a shepherd’s flute, so he put both his fingers in his ears and moved aside from the path. He kept saying: “O Nafi! Do you still hear the sound?” I would reply, “Yes!” When I said, “Now I do not hear it,” he returned to the path. Then he said, “I saw the Prophet Muhammad (peace and blessings be upon him) doing the same.”
