Is it permissible to remove the fetus from the womb of the sick wife after four months to place it in a special incubator to complete its development?

There is no objection to performing surgery to extract the fetus and place it in a special incubator to preserve its life if there is fear of its death by remaining in its mother's womb, due to the generality of the Almighty's saying: "And whoever saves a life – it is as though he had saved all mankind." It is also permissible to incise the mother's abdomen to save the fetus, because the harm of incising the abdomen is lesser than the harm of destroying the child. The jurisprudential rule states: "If two harms conflict, the greater of them is averted by committing the lesser." And preserving the life of the fetus is a greater benefit than the harm of violating the mother's sanctity.

Among the cases of necessary surgical delivery are: ectopic pregnancy surgery to save the mother's life, surgery to extract a live fetus after its mother's death to save the fetus's life, and a Cesarean section in case of uterine rupture to save the lives of both the mother and the fetus. These surgeries are legislated and permissible because they aim to save a protected life and remove harm, and some jurists consider them a mandatory obligation upon the physician.
