Quran 60:11 from Surah Al-Mumtahana on Divine Marvels.
وَإِن فَاتَكُمْ شَىْءٌۭ مِّنْ أَزْوَٰجِكُمْ إِلَى ٱلْكُفَّارِ فَعَاقَبْتُمْ فَـَٔاتُوا۟ ٱلَّذِينَ ذَهَبَتْ أَزْوَٰجُهُم مِّثْلَ مَآ أَنفَقُوا۟ ۚ وَٱتَّقُوا۟ ٱللَّهَ ٱلَّذِىٓ أَنتُم بِهِۦ مُؤْمِنُونَ
English translation: And if you have lost any of your wives to the disbelievers and you subsequently obtain [something], 1 then give those whose wives have gone the equivalent of what they had spent. And fear Allāh, in whom you are believers.
Transliteration: Wa-in fatakum shay-on min azwajikumila alkuffari faAAaqabtum faatoo allatheenathahabat azwajuhum mithla ma anfaqoo wattaqooAllaha allathee antum bihi mu/minoon
