Sindbad-Namah (981–1242 AD) was a collection of tales published before the Mongol invasion of Iran. The stories have been passed from generation to generation through oral and written tradition, and are the origin of the Sindbād-nāmah (The Book of Sindbad, or The Book of Seven Viziers). The Arabic version of the story existed during the Samanid era and the Persian version was published prior to the Mongol invasion. According to the Arab Historian Al-Masudi the story of Sindbad and the Seven Viziers originated in the Muslim Kurush region of Sindh.
The main character in the epic story is the Grand Vizier Sindbad of Mansura, Sindh. He defends the young prince from an adulterous accusation by his step-mother the Queen. The Vizier explains seven incidents in seven stories and saves the Samanid Dynasty from an eminent rebellion and collapse.
