Is the wife's refusal to take the labor-inducing injection, which led to delayed delivery and the death of the fetus after its condition had been good, considered her participation in the death, and is she sinful?

There is no sin upon the woman, nor is anything required of her, because she did not intentionally abort the fetus, nor was she aware. And if her husband suggests the matter of induced labor, she is not obligated to do so unless a trustworthy doctor informs her that not taking the injection will lead to the death of the fetus. If the doctor informs her of that and she does not act, then she is sinful.
