Is the mother considered sinful if she aborted her fetus in the seventh month based on the advice of doctors and a religious scholar who confirmed the impossibility of its life due to severe birth defects, and the fetus died immediately upon birth?

If the doctor and the mufti advise performing a delivery operation with the fetus placed in an incubator, then there is no sin upon the mother for what occurred; because it is not considered a forbidden abortion, but rather the extraction of the fetus alive for its benefit and the benefit of its mother.
