Sayyiduna Abu Hurayrah (may Allah be pleased with him) says that a man was driving a garlanded sacrificial camel, and the Messenger of Allah (peace and blessings be upon him) said: "Ride it." He said: O Messenger of Allah, it is a sacrificial animal. He (peace and blessings be upon him) said: "Woe to you, ride it! Woe to you, ride it!"
