60:10. O believers! When believing women come to you as emigrants, test their intentions. Allah knows best (the state of) their faith. Then, if you ascertain them to be faithful women, do not send them back to the disbelievers. These women are not lawful for those (idolators), nor are they lawful for them. And repay the disbelievers whatever (dowries) they have paid (to these believing women). There is no sin upon you in marrying them when you have given them their bridal gifts. Do not hold to the (marital) ties with disbelieving women. And demand (the disbelievers for repayment of) whatever you have spent (upon them as dowries), and let the disbelievers demand you for whatever they have spent. That is Allah’s judgement; He judges between you. And Allah is All-Knowing, All-Wise.

يا أيها الذين آمنوا إذا جاءكم المؤمنات مهاجرات فامتحنوهن الله أعلم بإيمانهن فإن علمتموهن مؤمنات فلا ترجعوهن إلى الكفار لا هن حل لهم ولا هم يحلون لهن وآتوهم ما أنفقوا ولا جناح عليكم أن تنكحوهن إذا آتيتموهن أجورهن ولا تمسكوا بعصم الكوافر واسألوا ما أنفقتم وليسألوا ما أنفقوا ذلكم حكم الله يحكم بينكم والله عليم حكيم
