Ruling on moving the marker of an old grave to a new grave

Q: Is it permissible to move the marker of an old grave to a new grave?

A: What appears to me from the pure Shari'ah is that this is not permissible; because it is a sign for the first grave. When people see it, they respect it, so they do not step on it, sit on it, or place filth on it. Therefore, moving it is a waste of its sanctity. The new grave is not in dire necessity of it; rather, it is possible to place another marker on it. If nothing is found, there is no blame in it remaining without a marker, provided it is raised from the ground by the height of a hand-span in the form of a grave. And success is from Allah.
