Question
A woman who is pregnant with twins and loses one of them after four months, her ruling as you mentioned is that she is considered postpartum from the first child and not the second. Does she forfeit prayer and fasting until she becomes pure after 40 days from the birth of the second child?
Answer
I say, and with God's success: She is in postpartum bleeding after the first child; if the second child comes after forty days, there will be no postpartum bleeding after him, and God knows best.
