Once, someone asked Sayyiduna Ali (may Allah be pleased with him) whether a person can ride the sacrificial animal—called Hadi—that he is taking for sacrifice during Hajj. He replied: There is no harm in it. Whenever the Prophet (peace and blessings be upon him) passed by those who were walking, he would instruct them to ride the Hadi animal, and you will not be able to follow anything superior to the Sunnah of your Prophet (peace and blessings be upon him).
