Musnad Abu Ya'la al-Mawsili 159:59

And from Abu Hurayrah, that the Messenger of Allah (may Allah bless him and grant him peace) saw a man driving a sacrificial camel. He said, "Ride it." He said, "It is a sacrificial camel." He said, "Ride it." He said, "It is a sacrificial camel." He said, "Woe to you, ride it."
