What are the rulings pertaining to blood that flows due to sexual intercourse and continues for several days, concerning ghusl (ritual bath), prayer, fasting, and sexual intercourse?

The blood a woman sees is divided into categories: menstrual blood (hayd), irregular bleeding (istihada), postpartum bleeding (nifas), and blood resulting from defloration or phlebotomy.

If the blood is istihada, then what is obligatory for the woman is what is obligatory for one with istihada: she must cleanse herself and perform ablution for every prayer. If it is continuous, she should use a protective measure (e.g., a pad), perform ablution after the prayer time begins, and then pray. This blood does not necessitate a ritual bath (ghusl) nor does it prohibit intercourse. Prayer and fasting are obligatory with it.

However, if the blood is hayd, then upon seeing it, it becomes forbidden for the woman to pray, fast, and engage in sexual intercourse. She must perform a ritual bath after it ceases.
