Sultan Satuq Bughra Khan is the founding saint of Islam among the Turks of the Tarim, a semi-historical Karakhanid khan who became the hero of a rich Uyghur hagiographic tradition. In the tazkirah his calling comes on the hunt: he chases a hare that turns to face him and becomes a holy man, in many versions the immortal Khidr, who summons him to the faith. Converting first in secret and then openly, he wrests the throne, wages holy war against his unbelieving kin, and brings his people to Islam. Around his tomb-shrine at Artush near Kashgar grew one of the foremost mazars of the Uyghur pilgrimage landscape, where the saint is still petitioned for intercession, binding the memory of the first Muslim khan to the living cult of the shrines.
