Is a divorce considered valid if the husband says to his wife: "By Allah, I will divorce you; in fact, I have already divorced you, and it is my intention to divorce you," should he claim he did not intend divorce, and is he accountable before Allah for this, given that it is the third divorce?

The husband's statement to his wife, "By Allah, I will divorce you, and it is my intention that I will divorce you," is a promise of divorce and does not constitute a divorce, but the husband must offer expiation for breaking an oath. As for his statement, "I have already divorced you," this is a declaration of divorce. If he is lying, then the divorce does not take effect religiously. Based on this, the divorce has not occurred, and the mentioned phrases do not constitute a divorce as long as the husband is lying, and she remains under his marital bond.
