believers when believing women come to you as emigrants test them. allah best knows their belief. if you find them to be believers do not return them to the unbelievers they are not permitted to the unbelievers nor are the unbelievers permitted to them. but give back to the unbelievers what they have spent and there is no fault in you to marry such women provided you give them their dowries. do not hold on to the ties with unbelieving women ask what you have spent and let them ask what they have spent. such is the judgement of allah he judges between you and allah is the knower and the 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
