Concept:Talaq al-ba'in is an irrevocable type of divorce in Islamic law.
Explanation:Islamic law recognises two main forms of divorce: revocable (talaq al-raj'i) and irrevocable (talaq al-ba'in).
The word "ba'in" means complete separation, so the marriage comes to an immediate end.
The husband has no right to take back his wife during the waiting period (iddah).
If both parties wish to reunite, they cannot simply resume the marriage.
They must contract a fresh nikah with a new marriage agreement.
This shows that talaq al-ba'in is not a temporary or reversible divorce.
It is final in nature, and reunion requires a completely new marriage contract.
