The ruling on a man saying to his wife, "We will be brothers or sisters"

Question:
This questioner says: There were arguments between me and my wife regarding the cleanliness of the house, caring for the children, and her neglect of the religion of Allah. When I would advise her, she would send for her parents, and they would reprimand me and scold me. She did this several times. In the last instance, I said to her: If you continue to wrong me and remain like this, and you insist on this—every time I advise you, you send for your parents—then it is better that we be brothers or sisters. I said this only with the intention of warning and frightening her. I left her and traveled for work. I now wish to return to my country. What is your honorable opinion on my saying to her, "We will be brothers or sisters," given that there has been no contact or correspondence between us during the entire past period?

Answer:
This is not a divorce. This is a matter of warning, a matter of warning, and there is nothing wrong with it. It is a matter of warning; it is not a divorce by this. However, if you say, "If you do such-and-such, you are divorced," or "You are forbidden to me," then there is a distinction. If your intention was to prevent her, this becomes an expiation for an oath. If you intended to frighten her, saying, "I will inform your family," and you sincerely intended to prevent her and take her away, then its ruling is the ruling of an oath: an expiation for an oath. But if you did not say anything, the best thing is to say, "Let us be brothers." This does not constitute a divorce. This does not amount to anything. This is an admonition. This is an admonition for the sake of Allah, an admonition and a reminder. Yes.
