Musannaf Ibn Abi Shayba 27:835

Ibn Fudayl narrated to us, from Abu Sinan, from Husayn al-Muzani, who said: Umar ibn al-Khattab said: "The likeness of the Arabs is only that of a camel with a nose-ring, following its leader. So let its leader look to where he is leading it. As for me, by the Lord of the Kaaba, I shall surely carry them upon the path."
