Qutb-al-Din's stay in Maragha was short. Subsequently, he traveled to Khorasan in the company of al-Tusi where he stayed to study under Najm al-Din Katebi Qazvini in the town of Jovayn and become his assistant. Some time after 1268, he journeyed to Qazvin, Isfahan, Baghdad and later Konya in Anatolia. This was a time when the Persian poet Jalal al-Din Muhammad Balkhi (Rumi) was gaining fame there and it is reported that Qutb al-Din also met him. In Konya, he studied the Jam'e al-Osul of Ibn Al-Athir with Sadr al-Din Qunawi. The governor of Konya, Mo'in al-Din Parvana appointed him as the judge of Sivas and Malatya. It was during this time that he compiled the books the Meftāḥ al-meftāh, Ekhtiārāt al-moẓaffariya, and his commentary on Sakkāki. In the year 1282, he was envoy on behalf of the Ilkhanid Ahmad Takudar to Sayf al-Din Qalawun, the Mamluk ruler of Egypt. In his letter to Qalawun, the Ilkhanid ruler mentions Qutb al-Din as the chief judge. Qutb al-Din during this time collected various critiques and commentaries on Avicenna 's Canon and used them on his commentary on the Kolliyāt. The last part of Qutb al-Din's active career was teaching the Canon of Avicenna and the Shefa of Avicenna in Syria. He soon left for Tabriz after that and died shortly after. He was buried in the Čarandāb cemetery of the city.
