It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) once saw a man driving a camel. The Noble Prophet (peace and blessings be upon him) said to him: "Ride on it." He replied, "It is a sacrificial animal." The Noble Prophet (peace and blessings be upon him) again said: "Ride on it." He again replied, "It is a sacrificial animal." And the Noble Prophet (peace and blessings be upon him) again ordered him to ride on it.
