The World Federation One Stop Fiqh

Ruling 608

If a [pregnant] disbelieving woman dies and the baby in her womb has also died, in the event that the father of the child is a Muslim, the woman must be laid on her left side with her back facing qibla so that the front of the baby faces qibla. The same applies, based on recommended precaution, if the spirit (rūḥ) has not yet entered the foetus.
