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.”
