Jalaluddin also kept good relations with Barsbay, the Mamluk sultan.[14] According to Al-Sakhawi's Al-Daw al-lami` li ahli al-Qarni al-Tasi, Barsbay once gifted the Bengali sultan with investiture, a robe of honour and a letter of recognition.[15][16] Jalaluddin had died before his own gifts could be dispatched to Barsbay and this job was left for his son, Shamsuddin Ahmad Shah, to be completed.[17]
