Is the divorced woman obligated to return what the husband spent on her after their divorce and before consummating the marriage? Is this divorce revocable or irrevocable? Does she have to observe an 'iddah? And is she entitled to refuse reconciliation?

If a man divorces his wife before consummation, she is not required to observe an 'iddah (waiting period). The divorce is considered irrevocable, meaning the husband cannot take her back except through a new marriage contract, and the woman has the right to refuse to return to him. If the divorce was not in exchange for compensation, she is not obligated to pay him anything; rather, she is entitled to the rights of a woman divorced before consummation.
