There was once a king who went out travelling about his kingdom in the clothes of a poor and humble man in order to observe the conditions of his people. Eventually he journeyed into the desert where he soon became tired, hot and thirsty. Luck was with him, however, and he reached the door of an Arab tent.
The Arab found him outside, exhausted from heat, thirst and hunger, and pulled him inside into the shade. When the king had revived he asked the Arab for food and drink, which was duly brought to him.
The king now regretted travelling in disguise and wished he was back in his palace. He wished to have the Arab help him to return, but fearing that the Arab would not believe him if he announced who he was straight away, he decided to broach the subject gradually.
