What is the ruling on the the prayers of a woman who stopped praying because she believed that menstrual or postpartum bleeding would resume after forty days from childbirth, then the bleeding stopped and returned again?

What the questioner saw is postpartum bleeding (nifas), not irregular bleeding (fasad), because it recurred before the completion of forty days, and there was no minimum period of purity separating it from the postpartum bleeding. Therefore, her cessation from prayer is correct, and she does not have to repeat the prayers. And know that scholars have differed concerning the ruling on the periods of purity that interrupt postpartum bleeding.
