How can justice be achieved between wives in treatment and laughter, and must the treatment and laughter with the second wife be exactly identical to the treatment and laughter with the first wife, even if circumstances or situations differ?

A man must be just among his wives by equalizing the division of nights spent with each, and by treating all of them kindly. He must repent for any mistreatment of any of them and show kindness to all. However, equalizing playfulness, affection, and similar matters is not obligatory.
