Al Mumtahanah, 11 Ayah
60:11
وَإِن فَاتَكُمۡ شَيۡءٞ مِّنۡ أَزۡوَٰجِكُمۡ إِلَى ٱلۡكُفَّارِ فَعَاقَبۡتُمۡ فَـَٔاتُواْ ٱلَّذِينَ ذَهَبَتۡ أَزۡوَٰجُهُم مِّثۡلَ مَآ أَنفَقُواْۚ وَٱتَّقُواْ ٱللَّهَ ٱلَّذِيٓ أَنتُم بِهِۦ مُؤۡمِنُونَ ١١
Wa 'In Fātakum Shay'un Min 'Azwājikum 'Ilá Al-Kuffāri Fa`āqabtum Fa'ātū Al-Ladhīna Dhahabat 'Azwājuhum Mithla Mā 'Anfaqū ۚ Wa Attaqū Al-Laha Al-Ladhī 'Antum Bihi Mu'uminūna
And if you have lost any of your wives to the disbelievers and you subsequently obtain [something], then give those whose wives have gone the equivalent of what they had spent. And fear Allah, in whom you are believers.
