Question
Does a woman rely on her usual duration of menstruation for her purity from menstruation and her washing, or on the cessation of blood for a period of time, knowing that there may be a period of purity between menstrual blood for a day or two?
Answer
I say, and with God's success: She relies on the true purity after the days of her habit have passed, and as for the purity during menstruation, it has the ruling of menstruation. And God knows best.
