What is the ruling if a man says to one wife: 'If you swear by divorcing your co-wife, she is divorced,' and then says to the second wife: 'If you swear by divorcing you, you are divorced'?

Primary text

The second wife is divorced immediately. Subsequently, if he says to the first wife what he initially said to her, or if he says to the second wife what he initially said to her, the second wife is divorced, and this applies up to the third time. No divorce takes effect upon the first wife through these subsequent statements because the oath in both instances is conditioned upon the divorce of the second wife.
