Divorce may be (pronounced) twice, then keep (them) in good fellowship or let (them) go with kindness; and it is not lawful for you to take any part of what you have given them, unless both fear that they cannot keep within the limits of Allah; then if you fear that they cannot keep within the limits of Allah, there is no blame on them for what she gives up to become free thereby. These are the limits of Allah, so do not exceed them and whoever exceeds the limits of Allah these it is that are the unjust.

O you who believe! when believing women come to you flying, then examine them; Allah knows best their faith; then if you find them to be believing women, do not send them back to the unbelievers, neither are these (women) lawful for them, nor are those (men) lawful for them, and give them what they have spent; and no blame attaches to you in marrying them when you give them their dowries; and hold not to the ties of marriage of unbelieving women, and ask for what you have spent, and kt them ask for what they have spent. That is Allah's judgment; He judges between you, and Allah is Knowing, Wise.
