Is it permissible to reconcile with one's wife after divorcing her for the second time, knowing that the husband had intended to divorce her with the triple repudiation to threaten her family, but did not utter it?

Divorce does not occur by mere intention; rather, it requires an explicit verbal utterance or an implicit statement accompanied by the intention. If a husband divorces his wife with a single pronouncement, he has the right to take her back as long as her waiting period ('iddah) has not ended. Otherwise, he may marry her again with a new marriage contract if she consents. The husband's statement to her parents that the divorce will be by three pronouncements has no effect, because it is a threat of divorce and not an actual divorce.
