What is the ruling regarding a man saying to his wife: "You are unlawful for me" or "I have made you unlawful for me," whether with the intention of divorce, or without intention, or if the word slipped from his tongue inadvertently?

The preponderant opinion regarding one who says to his wife: "You are unlawful to me" or "I have made you unlawful to me," intending divorce, is that his wife is divorced by this statement. If he did not intend anything, then it is an oath. However, if he uttered these phrases unintentionally, such as his tongue slipping, or he uttered them unconsciously due to extreme anger, then it is a mere slip of the tongue (laghw) and no unlawfulness, divorce, or oath results from it.
