A man who has two wives and forbids one from going out, then the one he did not forbid goes out and he says: so-and-so, you went out, you are divorced

Al-Hasan (may Allah have mercy on him) was asked: A man has two wives and forbids one of them from going out, but the other wife, whom he had not forbidden, goes out; he thinks it is the one he forbade, so he says, "So-and-so, you went out? You are divorced." What is the ruling? He said: The one he intended is divorced.

Ibrahim (may Allah have mercy on him) said: If a man has two wives and forbids one of them from going out, but the other wife, whom he had not forbidden, goes out; he thinks it is the one he forbade, so he says, "So-and-so, you went out? You are divorced" — in this case both are divorced: the one he named because of his naming her, and the other because of his saying to her, "You are divorced."

Al-Zuhri (may Allah have mercy on him) was asked: A man said to his wife, "If you go out, you are divorced." After that, a woman borrowed his wife's clothes, put them on and began to go out; her husband saw her and said, "You have gone out, so you are divorced." He said: This divorce falls on his wife.

Ata (may Allah have mercy on him) said: If a man swore an oath concerning his wife that she would not go out, but another wife of his went out, and someone said to him, "That is your wife," and he thought that perhaps she was the one he had forbidden from going out, and he divorced her, the divorce does not take effect.

Qatadah (may Allah have mercy on him) was asked: A man had two wives; one of them went out, and he asked, "Who is this?" He was told, "It is so-and-so." He said, "She is divorced," though she was not the one who had been named. What is the ruling? He said: Both of them are divorced.

Amir (al-Sha'bi) (may Allah have mercy on him) said: If a man had two wives or two slave-women, and he called one of them and said, "You are divorced," and the other one answered him, the one he named is divorced. And if he said it to his slave, the ruling is the same.
