Is swearing an oath of threefold divorce in a state of extreme anger, without intention or premeditation, that the wife shall not sit at the husband's personal device or his private social media account, considered a divorce? And is there expiation for it? And is it permissible to allow her to use a new personal device and her own social media account?

If you utter a divorce statement while being aware of what you are saying, then your divorce takes effect when you violate your oath. This is the view of the majority of scholars and the accepted practice, contrary to Ibn Taymiyyah, who holds that an oath of divorce not intended to effect divorce only necessitates an expiation for an oath. Divorce uttered as "triple" counts as one divorce.

The consideration in an oath is the intention and purpose of the swearer. If you intended to prevent your wife from entering a specific website, then she does not violate the oath by entering another website. However, if she enters the website you intended, then the fatwa we hold is that she is divorced by triple talaq. As for it being due to forgetfulness, we have given preference to the view that divorce does not occur.
