Is it possible to lift the restriction imposed on the wife's use of the computer with a single word, or must permission be renewed for each use, and is it permissible to nullify the restriction in secret without informing her?

The questioner made his wife's divorce contingent on her using the aforementioned device without his permission. The embarrassment is removed from the wife and the oath is fulfilled if he permits her to use the device absolutely. If the questioner did not intend to permit her every time before use, then no divorce occurs. However, if he did intend that, then divorce will inevitably occur unless he permits her every time before use.

The permission must be explicit and known to the wife; mere permission in the heart is not sufficient. Scholars have stated that permission must be explicit, and that merely knowing of her departure and not preventing her does not constitute permission. Some jurists have also held that a wife is divorced if she leaves without her husband's permission and is unaware of his permission. Jurists have differed on whether a wife is divorced if her husband permits her while she is asleep or absent and does not hear, and the correct view is that permission is only valid upon hearing.
