Is the wife considered irrevocably divorced (triple talaq), and can she be taken back after the husband uttered that at the police station?

Scholars have differed regarding one who swears to divorce his wife threefold, as mentioned in the question. The majority of scholars hold that the triple divorce occurs, while the Hanbalis—and this is what Ibn al-Qayyim preferred—are of the opinion that it does not occur. The preponderant view for us is that of the majority, as a precaution for religious matters. Therefore, she cannot return to him except after marrying another husband, or if this divorce was the first or second, then the husband may take her back before her iddah (waiting period) expires, according to those who hold that a triple divorce pronounced in a single utterance counts as a single divorce. It must be noted that divorce does not occur if the swearer was in a state of severe anger that led to loss of awareness. It is advisable to consult a Sharia court or trustworthy scholars.
