Question
A woman who becomes pure and then the blood returns to her, is it permissible for her to pray and for her husband to have intercourse with her on the days she is pure?
Answer
I say, and with God's success: If the blood returns to her within ten days from the start of her menstruation, then all of it is considered menstruation, and it is not permissible to have intercourse with her; because she is menstruating, and God knows best.
