What is the ruling on the small amount of blood that comes to a woman after her purification from post-natal bleeding and menstruation?

Question : The questioner says: Honorable Shaykh, a woman had post-natal bleeding, and after forty days she was purified, became pregnant, and fasted. She prayed and fasted, then afterwards she saw some drops of blood at scattered times, and it might stop for two or three days and then return. What is the ruling on her prayer and fasting, and if her husband has intercourse with her, what is the ruling on that?

Answer : If a woman is purified from post-natal bleeding or from menstruation, and then she sees one or two drops, or sees yellowish or brownish discharge, then that does not harm her and does not prevent her from fasting, prayer, or intercourse with her husband. This is because menstrual blood is known; it flows and gushes out in a flow, and it is known to the woman. As for one or two drops, they are not of menstruation in any way as long as they are after purification.
