What is the ruling for a woman with post-natal bleeding if she becomes pure before forty days?

Question : This questioner says: A woman became pure from post-natal bleeding after thirty-five days, and on the night of the forty-first day, blood came down on her. What is the comprehensive ruling regarding the past five days?

Answer : If a woman with post-natal bleeding becomes pure before the completion of forty days, it is obligatory for her to pray, and it is obligatory for her to fast if that is during Ramadan, and it is permissible for her husband to have intercourse with her even if the forty days have not been completed. So this woman who became pure after thirty-five days is required to fast and to pray, and whatever she fasted or prayed is valid in its place. If the blood returns to her after forty days, then it is looked at: if it coincides with her usual period, then it is her usual period; if it does not coincide with her usual period, then it is looked at in terms of distinguishing it, as is known in the books of the jurists (may Allah have mercy on them).
