2530. Irrevocable divorce means that after the divorce, the husband is not entitled to take back his wife, that is, he is not entitled to take her as his wife without Nikah. This divorce is of six kinds, namely:
1. The divorce of a woman who has not completed nine years of age.
2. The divorce of a woman who is in menopause.
3. The divorce of a woman whose husband has not had sexual intercourse with her after their marriage.
4. The third divorce of a woman who has been divorced three times.
5-6. The divorce called Khul'a and Mubarat.
Rules pertaining to these kinds of divorces will be detailed later. Divorces other than these are revocable, in the sense that as long as the wife is observing Iddah her husband can take her back.
