The long-reigning malik of Sistan, an old and well-regarded prince who has kept his small, rich delta kingdom through the Ghuzz troubles of the 1160s and the rise of the Ghurids by accepting Ghiyath al-Din as overlord, paying tribute and sending troops when called.
He rules from Zaranj with the fortress of Uq as his stronghold. His sons are grown men: Juzjani counts Nasir al-Din Uthman as the next malik, and Yamin al-Din Bahram Shah reigns from 1213. Juzjani, who knew the court, praises him as a just and generous king who honoured scholars.
