If a husband says to his wife, "You are divorced," then pauses for a few seconds, then returns and says, "Divorced, divorced," then denies uttering the divorce, is this considered one pronouncement of divorce or three?

Repeating the word of divorce three times without intending three divorces results in only one divorce, as stated by Al-Kharashi Al-Maliki: "You are divorced, divorced, divorced. Without reintroducing the subject; in this case, three divorces become binding... and the ruling of bindingness applies if he did not intend affirmation. But if he intended affirmation with the second and third utterances, then it benefits him and is accepted from him, and only one divorce becomes binding." Therefore, you have no right to leave your husband's house if you are not certain that three divorces have occurred. And as long as your husband denies the occurrence of divorce, his word is to be accepted.
