Alternately titled "The Two Sisters Who Envied Their Cadette" or "The Story of Two Sisters Who Were Jealous of Their Younger Sister."
Kosrouschah the Sultan is wandering the city in disguise when he hears three sisters talking about their hypothetical future husbands. Amused, he decides to make their daydreams come true, marries one to the royal baker, the second to the royal cook, and marries the third himself. However, the older two soon grow jealous of the younger. When she gives birth to a son, they set him adrift in the canal and replace him with a puppy. They repeat this with her second son and with her daughter. The Sultana is imprisoned and humiliated, but the three children are adopted by a gardener and grow up together. They are named Bahman, Perviz and Periezade.
An old woman tells Periezade about three magical objects: the Talking Bird, the Singing Tree, and the Golden Water. Prince Bahman goes to look for them, but is turned to stone. Perviz falls to the same fate. Periezade follows after them. Like them, she receives advice from a dervish, and hears about the voices that she must not respond to lest she turn to stone too. Unlike them, she stuffs her ears with cotton and manages to make the journey. She finds all of the magical objects and restores her brothers and all the other men who were turned to stone on their journey. Once they return home, the Talking Bird tells Periezade how to convince the sultan that she and her brothers are his true children.
