Musannaf Ibn Abi Shaybah 20192 — A man who swears by divorce to beat

Sa'id bin al-Musayyib (may Allah have mercy on him) and al-Hasan said: If a man says to his wife, "If I do not marry another woman over you, or if I do not send you out, you are divorced," then in this case the man may not approach his wife, and if they die before that, they will not inherit from each other.
