Which of the Prophet's wives and daughters did not perform 'Umrah?

The statement that some of the Prophet’s wives and daughters (peace and blessings be upon him) did not perform 'Umrah is far from accurate, as it is established that they performed 'Umrah and Hajj with him during the Farewell Pilgrimage (Hajjat al-Wada'). As for those who passed away before the Farewell Pilgrimage, it is unlikely that they did not perform 'Umrah. Furthermore, 'Umrah is not originally obligatory according to many scholars, so a person is not sinful for not performing it.
