وَإِن فَاتَكُمْ شَيْءٌ مِّنْ أَزْوَاجِكُمْ إِلَى الْكُفَّارِ فَعَاقَبْتُمْ فَآتُوا الَّذِينَ ذَهَبَتْ أَزْوَاجُهُم مِّثْلَ مَا أَنفَقُوا وَاتَّقُوا اللَّهَ الَّذِي أَنتُم بِهِ مُؤْمِنُونَ

If anything [of the dowries] pertaining to your wives is not reclaimed from the faithless and then you have your turn, then give to those whose wives have left the like of what they have spent, and be wary of Allah in whom you have faith.
