It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that once, while passing by a person, he saw that he was driving a camel. The Noble Prophet (peace and blessings be upon him) said to him, "Ride on it." He replied, "This is a sacrificial animal." The Noble Prophet (peace and blessings be upon him) again said, "Ride on it." Then I saw that he rode on it while there was a shoe hanging from the camel's neck.
