Should I pray after miscarrying an empty gestational sac in the fourth month, given that I experienced severe bleeding for three days during which I did not pray?

The ruling of nifas (postnatal bleeding) is established for a woman if she miscarries something in which human creation has become apparent. This typically occurs in the late third or early fourth month of pregnancy. If she miscarries a nutfa (sperm drop), the blood is considered dam fasad (corrupt blood) and not nifas. If the pregnancy reaches four months, it is nifas by consensus, because the soul has been breathed into it.

If she miscarries a formed mudgha (lump of flesh), it is considered nifas according to most scholars, because nifas is only established with certainty that human creation has become apparent. The minimum period for human creation to become apparent is 81 days. If the fetus is miscarried before that, there is no nifas, and the blood is istihadha (irregular bleeding). If it is miscarried after 81 days, it is necessary to ascertain whether it is formed or not. It is generally the case that if the pregnancy reaches 90 days, human creation becomes apparent within it.

However, if a woman miscarries an empty sac, this is not a fetus, and the discharged blood is not nifas. It does not prevent her from praying, and she must make up the prayers she missed.
