The details of this marriage is described by Hammer. At the Koltk (armchair) ceremony, when the bride and groom first meet upon her arrival at his konak, the princess, following the custom, disdained even to look at him and soon retired from the room. The eunuchs immediately removed the bridegroom's shoes and left them at the harem threshold, a ceremony indicating that he was now the harem's master. Eventually the bridegroom knelt before his bride and awaited her word in silence. Finally she said, "Bring me water." Having presented to her a cup of water while on his knees, he then asked her permission to raise her veil, which was embroidered and ornamented with pearls.
Meanwhile, slaves had brought in two food-laden trays, one with roast pigeon and the other with sweets. He offered her food which she imperiously rejected; then, he produced magnificent presents which assuaged her to the extent that he was able to lead her to the table for the ceremony of feeding each other. Later, when the festivities were over, eunuch Kıslar Ağası led him to her bedroom where he undressed cautiously, so as not to disturb her. He then sank to his knees beside her bed, and kissed her feet. In 1763, she was widowed by his death. In May 1764 she married, for the fifth and last time, Admiral Damat Ağa Mehmed Pashaun and remained his wife until his death in 1771, leaving her widowed until her death in 1778.
