Praise be to Allaah.
If the matter is as it is described, and she saw blood
when she was pregnant, five days before delivery, but she did not see any
other sign that delivery was imminent, such as labour pains or contractions,
then this blood is neither menstrual nor nifaas, but according to the
correct view it is a kind of irregular bleeding. On this basis, she should
not stop doing acts of worship, but she should fast and pray. If this
bleeding is accompanied by other signs of impending labour, such as
contractions and so on, then it is nifaas and so she should stop praying and
fasting, then when she is clean from it after giving birth, then she can
make up the fasts she has missed, but not the prayers.
