وَإِن فَاتَكُمْ شَىْءٌ مِّنْ أَزْوَٰجِكُمْ إِلَى ٱلْكُفَّارِ فَعَاقَبْتُمْ فَـَٔاتُوا۟ ٱلَّذِينَ ذَهَبَتْ أَزْوَٰجُهُم مِّثْلَ مَآ أَنفَقُوا۟ ۚ وَٱتَّقُوا۟ ٱللَّهَ ٱلَّذِىٓ أَنتُم بِهِۦ مُؤْمِنُونَ
wa-in fātakum shayon min azwājikum ilā l-kufāri faʿāqabtum faātū alladhīna dhahabat azwājuhum mith'la mā anfaqū wa-ittaqū l-laha alladhī antum bihi mu'minūna
If any of you have wives who leave you for the disbelievers, and if your community subsequently acquires [gains] from them, then pay those whose wives have deserted them the equivalent of whatever bride-gift they paid. Be mindful of God, in whom you believe.
And if any of your wives have gone from you to the disbelievers, (as apostates and you asked them to return back your Mahr but they refused) - then you went out for a Ghazwah (military expedition) (against them and) gained booty; then pay from that booty to those whose wives have gone, the equivalent of what they had spent (on their Mahr ). And fear Allâh in Whom you believe.
