Is a woman who has undergone a Cesarean section considered a postpartum woman (nufasaa'), and what is the ruling on her prayer?

The majority of scholars define post-partum bleeding (nifas) as blood that exits the woman's vagina after childbirth. If blood exits the woman's front private part due to childbirth, she is considered a woman in nifas, even if the birth was a Cesarean section. However, if no blood exits, she is not considered to be in nifas.
