Second Section – the Negative Commandments
45. It is a negative commandment "Do not curse a proper Jewish person"
As it states in Vayikra (Leviticus) 19:14, "do not curse a deaf person." When it speaks of a deaf person, it means to include others because this is true for a person who does not hear and is not hurt when he is cursed, but a person still transgresses this negative commandment if he curses him. If a person curses himself, he has also transgressed this negative commandment. A person does not transgress this commandment unless he curses using the name of G-d or one of His characteristics. If the curse was made using a name that used for G-d in another language, this counts as one of His characteristics.
This applies in all places and at all times, for men and for women.
