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