Quran 60:10 · Al-Mumtahanah

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِذَا جَآءَكُمُ ٱلۡمُؤۡمِنَٰتُ مُهَٰجِرَٰتٖ فَٱمۡتَحِنُوهُنَّۖ ٱللَّهُ أَعۡلَمُ بِإِيمَٰنِهِنَّۖ فَإِنۡ عَلِمۡتُمُوهُنَّ مُؤۡمِنَٰتٖ فَلَا تَرۡجِعُوهُنَّ إِلَى ٱلۡكُفَّارِۖ لَا هُنَّ حِلّٞ لَّهُمۡ وَلَا هُمۡ يَحِلُّونَ لَهُنَّۖ وَءَاتُوهُم مَّآ أَنفَقُواْۚ وَلَا جُنَاحَ عَلَيۡكُمۡ أَن تَنكِحُوهُنَّ إِذَآ ءَاتَيۡتُمُوهُنَّ أُجُورَهُنَّۚ وَلَا تُمۡسِكُواْ بِعِصَمِ ٱلۡكَوَافِرِ وَسۡـَٔلُواْ مَآ أَنفَقۡتُمۡ وَلۡيَسۡـَٔلُواْ مَآ أَنفَقُواْۚ ذَٰلِكُمۡ حُكۡمُ ٱللَّهِ يَحۡكُمُ بَيۡنَكُمۡۖ وَٱللَّهُ عَلِيمٌ حَكِيمٞ

O you who have believed, when the believing women come to you as emigrants, examine them. Allah is most knowing as to their faith. And if you know them to be believers, then do not return them to the disbelievers; they are not lawful [wives] for them, nor are they lawful [husbands] for them. But give the disbelievers what they have spent. And there is no blame upon you if you marry them when you have given them their due compensation. And hold not to marriage bonds with disbelieving women, but ask for what you have spent and let them ask for what they have spent. That is the judgement of Allah; He judges between you. And Allah is Knowing and Wise
