Did the major irrevocable divorce (baynunah kubra) occur upon divorcing the wife three times, knowing that the first and second divorces happened during menstruation and postpartum bleeding (nifas), and the third divorce occurred over the phone and in a state of extreme anger, and can the wife be taken back?

Divorce before consummation is an irrevocable divorce, meaning the husband has no right to reconcile with his wife, and she is not obligated to observe an 'iddah (waiting period). However, if a valid seclusion (khalwah sahihah) occurs after the marriage contract, it is considered equivalent to consummation according to the Hanbalis, and thus reconciliation becomes permissible. Therefore, if you reconciled with your wife after the first divorce based on the Hanbali juristic opinion, there is no sin upon you.

Divorce of a wife during her postpartum bleeding (nifas) is effective according to most scholars, and this is the adopted opinion (al-mufta bihi). Divorce of a pregnant woman is unanimously effective if her pregnancy is known. Anger does not prevent the occurrence of divorce as long as the husband is aware and acting voluntarily, and it is not a condition for its occurrence that the wife hears about it or knows about it.

Based on this, your wife has become irrevocably divorced from you by a major (triple) divorce, and she is not lawful for you unless she marries another man in a genuine marriage, and he consummates the marriage with her, and then divorces her or dies, and her waiting period (iddah) ends. We advise you to present this matter to trustworthy scholars in your country.
