Is it permissible to abort a fetus in its third month and a half if its heart is not fully functional, is not of its natural shape, does not distribute blood properly, and faces the risk of death at any moment, based on the doctor's recommendation?

Abortion is not permissible except in two cases: if the pregnancy poses a definite danger to the mother's life, which must be substantiated by a reliable medical report, or if the fetus has died in its mother's womb. Fetal illness or a poor heart condition does not justify abortion.
