In a given couple's lifetime, a divorce is permissible twice. (The whole period of divorce i.e. three menstruations / three months, or until delivery can be taken back twice). Then the divorced woman must be retained in honor or released in kindness. She shall be allowed to live in the same home amicably, or leave it amicably. At or after divorce, it is not lawful for you to take back anything of what you have ever given to her. However, if both of you fear that you might (in waves of emotion) transgress the bounds set by Allah, there shall be no blame on either of you if the wife willingly gives back whatever she chooses. These are the Limits set by Allah; transgress them not. Whoever transgresses the bounds set by Allah, such are the wrongdoers.
