Does the general permission to leave cancel the suspension of divorce on the wife leaving without permission, especially with the presence of the word "whenever" in the suspension formula?

As long as you have given your wife permission to go out whenever she wishes without seeking permission, then she does not break her oath if she goes out and does not need further permission. This is based on the statement in "Al-Sharh Al-Mumti'": "Not if he permits her in it whenever she wishes," and "So if he says to her: 'I have given you permission to go out whenever you wish,' the oath is dissolved at all times."
