Oaths by divorce and whether it is among the idle words of an oath

Question:
Among the questions that came to the program, Shaykh, this questioner says: A person frequently uses the word divorce on his tongue. He says to his colleagues at work, "I swear by divorce that you will eat with me" or "I swear by divorce that you will go with me to the open desert." We advised him, Shaykh, and he told us that this is among the idle words of an oath.

Answer:
No, divorce is serious whether it is serious or joking; it is not among the idle words. So the Muslim guards his tongue from uttering divorce because it is a dangerous word, and he may end up living with a woman who is not lawful for him because he divorced her with this divorce that comes from his tongue. Yes.
