Is there an expiation upon the wife for not fasting and praying on time after miscarrying a 9-11 week old fetus, given that she broke her fast for two weeks based on an incorrect fatwa, and is it permissible to make up the remaining days of prayer in the coming Ramadan?

If a wife miscarries a fetus that has formed after 81 days, she is considered to be in the state of nifas (postnatal bleeding) and must make up for any missed days of fasting, but not prayers. However, if the fetus has not formed before this period, her blood is considered istihadah (irregular bleeding) and does not prevent her from praying or fasting. She must make up for any missed prayers. There is no expiation required of her, only making up for the missed fasts, and she must hasten to make up for the missed prayers.
