What is the ruling on a husband's statement to his wife in a state of anger: "I swear by triple divorce, it will not stay (meaning: the car in the house)," concerning a car owned by the wife that she wishes to sell? Is it permissible for the husband to buy it from her after this oath, or must the car be removed from the house?

Most scholars are of the view that the divorce of an angry person is effective unless his mind is completely gone, and that an oath of divorce conditioned on a contingency makes the divorce effective upon the fulfillment of the contingency, and that a divorce pronounced three times counts as three divorces.

Accordingly, if the car did not leave the house as you intended in your oath, then your wife is divorced from you by three divorces. You cannot fulfill your oath by buying the car from your wife and leaving it in the house, because what you uttered does not allow for this scenario to be excluded from your oath.

However, according to the view of Ibn Taymiyyah, if you did not intend to effect a divorce with your oath, but rather intended to threaten or prevent, then in this case it is permissible for you to buy the car or leave it in your wife's possession and not remove it from the house, and no divorce occurs thereby, but you are required to offer an expiation for breaking an oath.

One must be cautious about swearing by divorce, as it is an oath of the wicked, and one should limit oneself to swearing by Allah Almighty.
