The fetus dying in an accident following its mother

Q: My car collided with another car leaving behind five deaths including a pregnant woman. The age of the fetus is unknown. The Permanent Committee issued a Fatwa no. (9691), dated 2/7/1046 A.H., stating that I have to fast for two consecutive months as expiation for each one of the five persons killed in this accident. Yet, it mentioned nothing concerning the fetus. (Part No. 21; Page No. 333) I hope you will tell me whether I have to fast as expiation for killing this fetus during the accident. Please, enlighten me as I am confused. May Allah guide you to all that is good!

A: If the reality is as you have mentioned, the mother and the fetus are regarded as one person as long as he died before birth.May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions!
