Is it permissible to abort a fetus in the sixth month due to hydronephrosis, oligohydramnios, and small size, given the doctors' confirmation that it will die at birth or before it, and is it permissible to stop future pregnancies due to the possibility of the same condition recurring?

It is impermissible to abort a fetus after four months, unless its continued presence poses a verifiable danger to the mother's life. However, if deformities recur in fetuses due to age or genetics, it is permissible to terminate the pregnancy due to hardship and the inability to achieve the intended purpose, provided the husband consents. If you decide to proceed with the pregnancy despite this, then be patient and seek reward from Allah if Allah decrees something undesirable; for in the death of children there is a great reward and a house in Paradise, and parents enter Paradise through their patience.
