Musannaf Ibn Abi Shayba 3:539

Ibn ‘Ulayyah narrated to us, from Ayyub, who said: I said to Sa’id ibn Jubayr, "Do you prevent anyone from passing in front of you?" He said, "No." I said, "But if he refuses?" He said, "Then what will you do?" I said, "It has reached me that Ibn ‘Umar would not let anyone pass in front of him." He said, "If you go and do what Ibn ‘Umar did, your nose will be broken."
