Recognizing the weakness of Timurid authority in Herat, Jahan Shah invaded and took the city on June 28, 1458, which was now occupied by Ibrahim Mirza's father, Ala al-Dawla Mirza. But Abu Sa'id Mirza could not tolerate this and after negotiations, Jahan Shah decided to return territorial demarcation to Shah Rukh's times. Thus, Khurasan, Mazandaran and Jurjan were returned to the Timurids and Abu Sa'id Mirza returned and took Herat a second time on December 22, 1458.
