O you who believe! when the believing women come to you having fled their homes, examine them. Allâh knows best the state of their faith. If you ascertain them to be (true) believers do not send them back to the disbelievers. These (believing women) are not lawful (wives) to those (disbelievers); nor are they lawful (husbands) to these (women). You shall however give them (their former disbelieving husbands) what they have spent on them. And you will be doing nothing unlawful if you marry these women after you have given them their dowries. And do not hold matrimonial ties with the disbelieving women, (should they join the disbelievers) you can claim what you have spent on them. So can (the disbelieving husbands) claim that which they have spent (on these believing women). This is the judgment of Allâh. He implements this judgment between you. Allâh is All-Knowing, All-Wise.
