What does Islam say regarding autopsy?

Performing an autopsy, on a human body voluntarily, is mutilating that body and forbidden according to shari’ah. In Abu Dawood, it is reported by our mother Hazrat Aisha (ra) that the Prophet Muhammad (saw) said:” Breaking the bones of a dead person is same like breaking them when he is alive.” But since the law exhorts us to perform autopsy in certain cases, thus in this case of an involuntary autopsy, we can only make dua that the dead person doesn’t suffer. Wallahou A’lam.
