lay a finger on

Make any contact

To lay a finger on someone is to touch them at all, almost always used in the negative to emphasize restraint or prohibition: Don't you dare lay a finger on her, He swore he never laid a finger on the child.

The phrase implies potential harm—the "finger" represents the minimal possible contact, so denying even that asserts complete physical innocence or warns against any aggression whatsoever.
