Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Prophet Muhammad (peace and blessings be upon him) held a race between horses. He had them race and set a finish line for the race. The Prophet Muhammad (peace and blessings be upon him) said: "The competition will only be between those horses that have hooves and are thoroughbred."
