The Golden Water, the Talking Bird, and the Singing Tree  (English, Paperback, Kumar Golu)

There was a Persia emperor named Kosrouschah who, when he first assumed the throne, took great joy in night journeys accompanied by a trusted minister in order to gain information of matters. He frequently went about the city in disguise and had several adventures, one of the most notable of which occurred on his first ramble, not long after his father's ascent to the kingdom.
