Musannaf Ibn Abi Shayba 3:2731

'Abbad ibn al-'Awwam narrated to us, from Yahya ibn Sa'id, from Nafi', that a son of Sa'id ibn Zayd ibn Nufayl was at a land of his in al-'Aqiq, a few miles from Medina. He met Ibn 'Umar on the morning of Friday and informed him of his complaint (illness). So he (Ibn 'Umar) set out to him and left the Friday prayer.
