O ye who believe! when there come believing women who have fled, then try them: God knows their faith. If ye know them to be believers do not send them back to the misbelievers;- they are not lawful for them, nor are the men lawful for these; - but give them what they have expended, and it shall be no crime against you that ye marry them, when ye have given them their hire. And do not ye retain a right over misbelieving women; but ask for what ye have spent, and let them ask for what they have spent. That is God's judgment: He judges between you, for God is knowing, wise!
