What is the ruling on the prayer of a woman who underwent uterine surgery, and blood continued to discharge for 15 days after the operation, not being during her menstrual period, and how does she make up her prayers?

If a woman ascertains that the blood in the post-operative period is Istihadah blood, then prayer and other acts forbidden to a menstruating woman are not prohibited to her because of it, and she must make up for missed prayers. The reliable doctors are the reference for knowing this. Istihadah is blood that is not caused by childbirth, defloration, a wound, medical treatment, or an ailment and corruption in the body.
