Question: Is the (pronouncement of) divorce by the one who is intoxicated carried out?
Response: We do not issue fatwa rulings in these matters, unless such an issue has actually occurred with a particular person.
However, the general rule is that this matter should be taken to the (sharee’ah) court. And if the court decides that the divorce is to be carried out, then it will be carried out; and if the court decides the divorce is not to be carried out, then it will not be carried out.
