The Women - 4:19
Believers! It is not lawful for you to inherit the property of women against their wishes. Do not press them to take back from them what you have already given them. Except when they commit fornication. Get along well with them. If you dislike them, Allah has put much good in what you dislike.
If the divorced woman commits adultery:
Divorce/65:1
O Prophet, when you divorce women, observe the term of divorce and calculate it well. Listen to Allah, your Lord. And do not drive them out of their homes, nor should they drive them out (do not force them to do so by ill-treatment). Except if they commit proven adultery. This is the law of Allah. Whoever transgresses Allah´s law has wronged himself. You do not know, but perhaps Allah will bring about something (positive) after that.
