O believers! When the believing women seek refuge with you, test them. Allah best knows their faith. If you find them true believers, do not send them back to the unbelievers. They are not lawful [wives] to the unbelievers, nor are the unbelievers lawful [husbands] to them. Return to their unbelieving husbands what they have spent on them. There is no blame on you if you marry such women, provided you give them their dowers. Do not hold on to your marriages with unbelieving women. Demand what you have spent on them and let the unbelievers do the same. This is the order of Allah which He has decreed between you. Allah is All-Knowing, All-Wise.
