Hadith.4469 - Al-Hasan ibn Mahbub narrated from Jamil ibn Salih that Abu Abdullah said regarding two sisters who were given in marriage to two brothers, but each was mistakenly sent to the other brother. Abu Abdullah said: "Each woman is entitled to the dowry due to consummation. If their guardian deliberately caused this mix-up, he must pay the dowry. Neither man may approach his wife until her waiting period ('iddah) ends. Once the waiting period is over, each woman returns to her original husband based on the first marriage contract." It was asked: "What if the women die before the waiting period ends?" Imam said: "The husbands may reclaim half of the dowry from their heirs, and the two husbands inherit from them." It was further asked: "What if the husbands die while the wives are still in the waiting period?" Imam said: "The wives inherit from their husbands and are entitled to half of the dowry. After completing the waiting period for the first incident, they must observe another waiting period as widows of their deceased husbands."
