It is narrated from Hazrat Anas (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 said, "It is a sacrificial animal." The Prophet (peace and blessings be upon him) said, "Even if it is a sacrificial animal."
