No. Since the card was already at [Stand], and when the card attacked, it was already at [Rest]. (Although if the card had double attack, or if the opponent has a spell to re-stand it again, then it wouldn't work. But, as for the impact... it's already too late. I recommend that you nullify that attack BEFORE the opponent gets to use the impact.)
