Is it permissible for a woman to call her husband by his name?

There is no harm in a wife calling her husband by his name, unless custom dictates otherwise or the husband dislikes being addressed by his name. In such cases, she must observe this for the sake of a good relationship. Both spouses should call each other by the names most beloved to them, as this strengthens love and affection. It is generally a good etiquette in companionship to address a person by the name most beloved to them.
