Is it permissible for a daughter to donate a piece of her liver which is required to be transplanted in her father?

Answer

It is absolutely haraam for the daughter to have a piece of her liver cut and be transplanted into the body of her father or of any person. Such mutilation is haraam. Don't be duped by these doctors with atheistic tendencies. All available remedies should be tried, and much dua made for recovery. Whatever Allah Ta'ala wills, shall transpire. A Muslim resigns himself/ herself to the decree of Allah Ta'ala.
