The Nāṣirī Generations 103: IX. MALIK SHIHAB-UD-DIN, MAHMUD, SON OF HARAB.

103

When the army of infidels, after having reduced it to desolation, turned their backs upon Sistan, Malik Shihabud-Din, who had kept in concealment, came forth and took possession of Sistan; but, as it was in a very ruinous state, and no inhabitants remained, he did not acquire much strength or power.
A party of heretics gathered together in some force, and besought Shah ’Usman, the grandson of Nasir-ud-Din, ’Usman, Taj-ud-Din-i-Harab, to come from the city of Neh, and occupy Sistan. He called in the aid of a force of Khwarazm-Shahi troops, from the Malik of Kirman, whom they styled Burak, the Hajib [chamberlain]. When that body of troops, from Kirman, joined Shah ’Usman and came to Sistan, Shihab-ud-Din, Mahmud, was martyred, and his brother, Amir ’Ali-i-Zahid [a recluse, a holy man], ascended the throne. Still the government did not acquire stability, and he died.
