Al Utbi, the author of Tarikh-i-Yamini, writes how Sultan Mahmud punished Nawasa Shah: "Satan had got the better of Nawasa Shah, for he was again apostatizing towards the pit of plural worship, and had thrown off the slough of Islam, and held conversation with the chiefs of idolatry respecting the casting off the firm rope of religion from his neck. So the Sultan went swifter than the wind in that direction, and made the sword reek with the blood of his enemies. He turned Nawasa Shah out of his government, took possession of all the treasures which he had accumulated, re-assumed the government, and then cut down the harvest of idolatry with the sickle of his sword and spear. After God had granted him this and the previous victory, which were tried witnesses as to his exalted state and proselytism, he returned without difficulty to Ghazna.”.
