What is the expiation for aborting a fetus in its second month out of fear of the husband, and does it include fasting during menstruation?

Abortion is a grave sin that necessitates repentance from the mother and her husband, if he ordered it. Fear does not justify abortion. If abortion occurs after the fetus has been formed, blood money (diyyah) is obligatory. This is a "ghurrah," valued at five camels, and it must be paid by whoever carried out the abortion. Expiation (kaffarah) is also obligatory according to the majority of scholars, which is the freeing of a slave. If that is not possible, then fasting for two consecutive months, uninterrupted by menstruation.
