Musannaf Ibn Abi Shaybah 19235 — A man who means to say something, but

Amir (al-Sha'bi) (may Allah have mercy on him) and al-Hakam (may Allah have mercy on him) were asked: If a man wants to say something to his wife but by mistake utters words of divorce to her, what is the ruling? Al-Sha'bi (may Allah have mercy on him) said: It is nothing, whereas al-Hakam (may Allah have mercy on him) said: The divorce takes place.
