The ruling on the prayer of a woman whose menstruation comes intermittently due to an IUD

Question:
Honorable Shaykh, may Allah grant you success. This is a woman asking, and she says: A woman has had an IUD inserted, and her menstruation has become intermittent; sometimes it comes once a day. Does she pray during the dry periods? Or what does she do?

Answer:
If it comes to her for a short period, it has no ruling; she prays, and it has no ruling. But if it comes to her and continues for a period of a day or a day and a night, this is considered menstruation, and she leaves off the prayer during that time. When it stops, she performs the full ritual bath and prays during the dry periods. Yes, she is considered menstruating during the time the menses are flowing, and pure when they stop. I advise women not to mess with themselves by taking pills or having an IUD inserted or the like; because this puts them in difficulty and causes them confusion and hardship. May Allah protect them from this.
