Hoşyar Kadın was the adopted daughter of Beyhan Sultan, daughter of Sultan Mustafa III, and cousin of the Sultan Mahmud. In 1811, Beyhan Sultan gave a grand banquet to Mahmud. During this time, he offered Hoşyar's hand in marriage to him. Beyhan consented to his offer and after some days sent her to the imperial harem, with great ceremony, and with magnificent presents, which she gave her as her dower. For ten days the Sultan was most assiduous in his attentions, after that period he showed himself no more.

On 29 June 1812, she gave birth to her only daughter, Mihrimah Sultan. When the time came to get her a husband, Hoşyar resolved that she should make her choice. She showed her the portraits of several young men, each worthy of her hand. She fixed upon Said Pasha. Very few months had elapsed, when Mihrimah already enceinte, died in 1838, and with her Hoşyar's last solace disappeared.Bezmiâlem Sultan, the mother of Sultan Abdulmejid I always regarded her with a jealous eye. She scarcely allow her to receive, once a month, a visit from Said Pasha when he was at Istanbul. Moreover, she was never allowed to hear of her daughter spoken of.

In later years she settled in her palace, situated at Tarlabaşı, facing Dolmabahçe Palace. She also met Melek Hanim, wife of grand vizier Kıbrıslı Mehmed Emin Pasha. Melek described her being tall and fair haired, and her skin, extremely white, set off the freshness of her complexion. Knowing that she had been in Europe, she interrogated her as to the manners and customs of the Christians, the way the towns were built, the balls, theatres, systems of lighting by gas, architecture of the palaces, and a thousand other matters. In 1859, she went for a pilgrimage to Mecca, where she died.
