Does a divorce, pronounced twice in a moment of extreme anger with the intention of threat and not actualization, take effect? Is expiation required for that, given the inability to recall whether the three pronouncements were completed?

If you utter a divorce statement while being fully aware of what you are saying, it is considered effective against your wife, regardless of whether it is an immediate divorce or one conditioned upon the fulfillment of a contingency. This is the view of the majority of scholars. As for doubting whether a third divorce has occurred, it is not taken into consideration, because a divorce does not take effect based on doubt. We caution against using divorce pronouncements as a threat.
