Does a divorce occur if the husband says, "Haniyya, you are divorced, my darling," while singing a song that contains these words, given that his wife's name is not Haniyya, and knowing that what he said were the lyrics of a song without music?

The husband's repetition of song lyrics containing the word "divorce" does not result in divorce, because it does not indicate intent, and because the word is directed at someone other than the wife. Divorce must be attributed to the wife either by an explicit pronouncement or by an indirect expression accompanied by the intention to divorce.
