Is light bleeding upon wiping the uterine area after a hysterectomy (with the cervix remaining) at the time of the menstrual period considered istihadah?

The basic principle is that a complete hysterectomy severs the menstrual blood. However, as long as the cervix has not been removed and the light bleeding coincides with the time of the menstrual period, it is considered menses if it lasts for a day and a night, especially if it possesses the characteristics of menstrual blood. The questioner should consult a doctor to determine the source of the bleeding and whether it is menstrual blood or istihadah (definition) (irregular vaginal bleeding outside of menstruation).
