Al-Mumtahanah 60:10 يا ايها الذين امنوا اذا جاءكم المومنات مهاجرات فامتحنوهن الله اعلم بايمانهن فان علمتموهن مومنات فلا ترجعوهن الى الكفار لا هن حل لهم ولا هم يحلون لهن واتوهم ما انفقوا ولا جناح عليكم ان تنكحوهن اذا اتيتموهن اجورهن ولا تمسكوا بعصم الكوافر واسالوا ما انفقتم وليسالوا ما انفقوا ذالكم حكم الله يحكم بينكم والله عليم حكيم ١٠

You who believe, test the believing women when they come to you as emigrants- God knows best about their faith- and if you are sure of their belief, do not send them back to the disbelievers: they are not lawful wives for them, nor are the disbelievers their lawful husbands. Give the disbelievers whatever bride-gifts they have paid- if you choose to marry them, there is no blame on you once you have paid their bride-gifts- and do not yourselves hold on to marriage ties with disbelieving women. Ask for repayment of the bride-gifts you have paid, and let the disbelievers do the same. This is God’s judgement: He judges between you, God is all knowing and wise.
