Musannaf Ibn Abi Shaybah

Hazrat Abu Ja'far, may Allah have mercy on him, was asked about a man who had four wives. One of his wives looked at him, so he said to her, "You are absolutely divorced." When he came to them, each one claimed that it was the other, and he could not recognize which one it was. What is the ruling? Hazrat Abu Ja'far, may Allah have mercy on him, said that all of them will be separated from him.
