Musnad Abu Ya'la al-Mawsili 115:327

Abu Musa narrated to us, Ibn Abi Adi narrated to us, from Sa'id, from Qatadah, from Anas, that the Prophet of Allah (may Allah bless him and grant him peace) came upon a man driving a sacrificial camel. He said, "Ride it." He said, "It is a sacrificial camel." He said, "Ride it, woe to you."
