2:187Permitted for you is intercourse with your wives on the night of the fast. They are a garment for you, and you are a garment for them. God knows that you used to betray yourselves, but He turned to you and pardoned you. So approach them now, and seek what God has ordained for you, and eat and drink until the white streak of dawn can be distinguished from the black streak. Then complete the fast until nightfall. But do not approach them while you are in retreat at the mosques. These are the limits of God, so do not come near them. God thus clarifies His revelations to the people, that they may attain piety.

2:229Divorce is allowed twice. Then, either honorable retention, or setting free kindly. It is not lawful for you to take back anything you have given them, unless they fear that they cannot maintain God's limits. If you fear that they cannot maintain God’s limits, then there is no blame on them if she sacrifices something for her release. These are God’s limits, so do not transgress them. Those who transgress God’s limits are the unjust.

2:230If he divorces her, she shall not be lawful for him again until she has married another husband. If the latter divorces her, then there is no blame on them for reuniting, provided they think they can maintain God's limits. These are God’s limits; He makes them clear to people who know.
