Рустем-паша
An Arabic foundation inscription on the mosque records that it was commissioned by Mehmed Beg b. Abu al-Saʿadat’ who was a brother of a vizier in the year AH 965 (1557-58). Some scholars have claimed that the vizier was the grand vizier Rüstem Pasha, but Rüstem Pasha is recorded as having only a single brother, Sinan Pasha.
