It is narrated from Hazrat Anas bin Malik (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) saw a man driving a sacrificial animal. The Prophet (peace and blessings be upon him) told him to ride it. He said, "This is a sacrificial animal." The Prophet (peace and blessings be upon him) told him two or three times to ride it.
