Is it permissible to re-shroud the deceased inside the grave if a visible part of a previous corpse is found when burying a new corpse?

It is not permissible to exhume a grave unless the body has completely disintegrated and turned to dust, or if there is a legitimate Sharia-compliant benefit. However, if the burial of a new deceased person has commenced and remains of the first deceased's body are found, these remains are to be returned to the grave and buried therein, and a new grave dug for the new deceased in another location, because breaking the bone of a deceased person is like breaking the bone of a living person.
