Over this period, Ibn Khaldun would have many meetings with Tamerlane and they would converse through an interpreter, Abd al-Jabbar al-Khwarizmi (d. 1403). Ibn Khaldun’s account is the only detailed account available. The subjects that they would discuss were varied and some were unrecorded. W. Fischel lists 6 specific topics which they talked about:
On Maghrib and Ibn Khaldun’s Land of origin.
On heroes in History.
On predictions of things to come.
On the Abbsid Caliphate
On amnesty and security "For Ibn Khaldun and his Companion."
On Ibn Khaldun’s intention to stay with Tamerlane.[32]
