Is abortion permissible if the fetus is afflicted with a hereditary disease such as thalassemia, and what should be the gestational age of the fetus when the abortion is performed, noting that thalassemia testing is done in the eleventh week of pregnancy?

Abortion is not permissible due to fetal illness or malformation. Rather, it is permissible in two cases: if the death of the fetus in its mother's womb is confirmed, or if the continuation of the pregnancy poses a danger to the mother's life. This ruling applies to the fetus at all stages, both before and after forty days.
