Believers, when believing women seek refuge with you, test them. God best knows their faith. If you find them true believers, do not return them to the infidels; they are not lawful for the infidels, nor are the infidels lawful for them. But hand back to the unbelievers the dowries they gave them. Nor is it an offence for you to marry such women, provided you give them their dowries. Do not maintain your marriages with unbelieving women: demand the dowries you gave them and let the infidels do the same. Such is the law which God lays down among you. God is all-knowing and wise.
