On Thursday, the nineteenth of Ramazan, 637 A.H. (April, 1240 A.D.), the Sultan Raziya returned to the capital. Malik Altuniya, who was governor of Tabarhindh, revolted, and some of the high officials on the frontier supported him. On Wednesday, the ninth of the same month and year, she marched with a numerous army toward Tabarhindh to put down these rebels. When she arrived there, she was attacked by the Turks, who put the Abyssinian Amir Jamal-ad-din Yakut to death. They then seized the Sultan Raziya and sent her a prisoner to the fort of Tabarhindh.When Sultan Raziya was taken to Tabarhindh as a captive, Malik Altuniya espoused her cause and led her army toward Delhi to regain possession of the kingdom, whereupon Malik Izz-ad-din Mohammad Salari and Malik Karakash left the capital and went to join them. Meanwhile, Mu’izz-ad-din had ascended the throne, Ikhtiyar-ad-din Itigin, the lord chamberlain, had been slain, and Badr-ad-din Sankar Rumi had been appointed his successor.
