Surah Al-Mumtahana, Verse 11
وَإِن فَاتَكُمْ شَىْءٌۭ مِّنْ أَزْوَٰجِكُمْ إِلَى ٱلْكُفَّارِ فَعَاقَبْتُمْ فَـَٔاتُوا۟ ٱلَّذِينَ ذَهَبَتْ أَزْوَٰجُهُم مِّثْلَ مَآ أَنفَقُوا۟ ۚ وَٱتَّقُوا۟ ٱللَّهَ ٱلَّذِىٓ أَنتُم بِهِۦ مُؤْمِنُونَ
Translation — Sahih International
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.
