Is the bleeding after forty days post-natal bleeding?

Question:
If the woman in the post-natal period becomes pure within the forty days, and then sees blood after the forty days, or if the blood continues with her until fifty days, what is the ruling?

Answer:
If the forty days are completed and the blood remains, she must perform the full ritual bath; because the end of post-natal bleeding is forty days according to the correct opinion. So when the forty days are completed, she must perform the full ritual bath, pray, fast, and become lawful to her husband. She must take precautions with cotton or the like against these bloods, and the blood becomes defective after that, being among the defective bloods. If it stops and then returns, and coincides with the time of her usual period, the time of the menstruation she knows, she sits for menstruation, the usual menstruation, she sits for menstruation, and it becomes menstruation, not post-natal bleeding.
As for this connected blood that continued with her, it is defective blood, so she takes precautions with cotton or the like, performs the full ritual bath, prays, fasts, and becomes lawful to her husband in this blood that exceeds the forty days; because the duration of post-natal bleeding is forty days, as in the hadith of Umm Salama. This is the correct opinion.
