Is it permissible for a man to take back his wife, whom he divorced with three pronouncements, because of a magic spell of separation found in his home?

If the husband utters the triple divorce of his own will, being fully aware of what he is saying, then his divorce is effective, and his wife becomes unlawful for him until she marries another husband, who then divorces her after consummating the marriage. However, if he utters the divorce while not being aware of what he is saying, or if his will was overwhelmed due to magic, then the divorce is not binding on him in these two cases.
