What is the ruling on abortion due to the pregnant woman's fear for herself and the fetus from potential deformities and disabilities, and does it necessitate an expiation while the pregnant woman is unable to fast for the expiation?

Abortion is not permissible due to fear of fetal deformity, and expiation is required for it, according to the more preponderant opinion. As for abortion due to fear for the mother's life, it is permissible if confirmed by a trustworthy physician and no other means are available, and expiation is not required for it. For one who wishes to offer expiation but finds fasting difficult, she may postpone it until she gives birth and finds an opportunity to fast.
