2 verses have

in Edition Clear Qur'an by Talal Itani / Al-Baqara (The Cow)

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.

2:231When you divorce women, and they have reached their term, either retain them amicably, or release them amicably. But do not retain them to hurt them and commit aggression. Whoever does that has wronged himself. And do not take God’s revelations for a joke. And remember God's favor to you, and that He revealed to you the Scripture and Wisdom to teach you. And fear God, and know that God is aware of everything.
