All the animals began to work for Man, but the Camel lived in a desert because he was idle and refused to help. The Dog, the Horse and the Ox all requested him to join them for work, but he always answered “Humph!” The other animals complained to the Man.The man said that he was sorry, but they will have to work for longer hours.
Then the animal decided to complain to the Djinn in charge of All Deserts. So the Djinn went to talk the Camel and asked him to work, but the only thing camel would say was “Humph!” The Djinn then made a magic that puffed up the Camel’s back into a humph (or hump) and punished him to work for three days without eating, living on his hump instead, to make up for the days he had missed. The Camel still has his hump, because he never did make up for the days he missed, and he still behaves badly.
