Divorce is permissible only twice (after an intermediate reconciliation); then keep them in honour, or let them go with kindness. It is not lawful for you to take from them anything of what you have given them, unless both fear that they cannot keep within Allah's bounds. So if you fear that you cannot keep within Allah's bounds there is no crime in you both if she ransoms herself. These are Allah's bounds. Do not transgress them; and whoever transgresses Allah's bounds, they it is who are unjust.
