Should a woman who aborted a fetus that was not clearly formed (consisting of flesh and blood) at three months minus one week of gestation pray, or does she have the ruling of nifas and menstruation?

If a woman aborts something that shows the formation of a human — even if subtly — the rulings of nifas (postnatal bleeding) apply to her. The minimum period in which human formation becomes apparent is 81 days. This is the predominant view of the Hanbalis, which aligns with the حديث (Prophetic tradition). In this case, she is considered a nufasa' (woman in postnatal bleeding) and must abstain from prayer and fasting until the bleeding stops or the nifas period ends. She then makes up for the missed fasts after she becomes pure.
