v3.c26.19

After his return to Māndū he was engaged in punishing robbers, and when he had completed this task he founded the city of Hoshangābād, on the Narbada. Here he was alarmed by an accident which he took for an omen of death. A ruby fell one day from his jewelled crown, and though his courtiers endeavoured to reassure him, an attack of diabetes confirmed his fears. He left Hoshangābād and returned to Māndū, and on his way thither designated his eldest son as his heir. A number of the nobles, to whom Ghaznī Khān was obnoxious, supported the pretensions of 'Usmān Khān, who had been imprisoned for having grossly insulted his elder brother, and intrigues were set on foot for his liberation, to which the king would not consent.
