 60:10

يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا جَاءَكُمُ الْمُؤْمِنَاتُ مُهَاجِرَاتٍ فَامْتَحِنُوهُنَّ ۖ اللَّهُ أَعْلَمُ بِإِيمَانِهِنَّ ۖ فَإِنْ عَلِمْتُمُوهُنَّ مُؤْمِنَاتٍ فَلَا تَرْجِعُوهُنَّ إِلَى الْكُفَّارِ ۖ لَا هُنَّ حِلٌّ لَهُمْ وَلَا هُمْ يَحِلُّونَ لَهُنَّ ۖ وَآتُوهُمْ مَا أَنْفَقُوا ۚ وَلَا جُنَاحَ عَلَيْكُمْ أَنْ تَنْكِحُوهُنَّ إِذَا آتَيْتُمُوهُنَّ أُجُورَهُنَّ ۚ وَلَا تُمْسِكُوا بِعِصَمِ الْكَوَافِرِ وَاسْأَلُوا مَا أَنْفَقْتُمْ وَلْيَسْأَلُوا مَا أَنْفَقُوا ۚ ذَٰلِكُمْ حُكْمُ اللَّهِ ۖ يَحْكُمُ بَيْنَكُمْ ۚ وَاللَّهُ عَلِيمٌ حَكِيمٌ ﴿١٠﴾

10. O you who believe! When believing women come to you emigrating, test them. Allah is Aware of their faith. And if you find them to be believers, do not send them back to the unbelievers. They are not lawful for them, nor are they lawful for them. But repay them what they had spent. You are not at fault if you marry them, provided you give them their dues. And do not hold to ties of unbelieving women, but demand what you had spent, and let them demand what they had spent. This is the rule of Allah—He judges between you. Allah is Knowing and Wise.
