It has been said before but bears repeating: “whatever is unintentional is permitted.”
For it was taught, R. Simeon said: One may drag a bed, seat, or bench (on Shabbat in a private domain), providing that he does not intend to make a rut!
But with some more detail:
Wherever there is a Scriptural interdict if it is intentional, R. Simeon forbids it by Rabbinical law even if unintentional; but wherever there is [only] a Rabbinical interdict even if it is intentional, R. Simeon permits it at the outset if unintentional.
Again, this is the tension in instances where there is clear Torah law (not making a rut) and subsequent rabbinic laws established to protect the Torah law from accidental violation. Here we see that intention is key. “Dragging” is permissible, even if it accidently makes a rut in a soft floor, so long as there is no intention to make the groove.
Think before you act!
