If a person is walking in a reshus harabbim or a karmelis on Shabbos and he kicks a pebble in the street a distance of dalet amos, did he transgress the melacha of carrying?
Is it considered Mis’asek, since he was just walking normally without intending to kick the pebble (and maybe not even realizing that it was there)?
He would not have transgressed any melacha. When one has no intent to do a melacha and it happens inadvertently he is not responsible for that melacha. This is as long as it was not a “psik reisha”, meaning that the melacha outcome was not obvious and certain from his actions.
