Is the second divorce pronouncement uttered by the husband under severe pressure and provocation from the wife, and in a state of exhaustion and fatigue, and without the intention of divorce, considered a valid divorce, taking into account that he was keen not to utter it, and that he took his wife back after two days, but now doubts its validity?

Pronouncing divorce during anger does not prevent its effectiveness, unless the anger reaches a level that removes perception and overwhelms the mind. Accordingly, if you pronounced divorce for the second time while you were aware of what you were saying and your mind was not overwhelmed, then your divorce is effective. By doing so, you would have completed three divorces, and your wife would have become irrevocably separated from you with a major (irrevocable) divorce. You cannot take her back unless she marries another man, consummates the marriage with him, and then he divorces her or dies, and her waiting period from him expires. It is advisable to present the matter to trustworthy scholars.
