A man who has intercourse with his wife's mother or his wife's daughter: what is his wife's status?

Sayyiduna Imran bin Husayn (may Allah be pleased with him) said: If a man has intercourse with his mother-in-law, his wife becomes forbidden to him.

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: They are two sanctities which he has transgressed, but that does not make them forbidden to him.

Sayyiduna Abdullah (bin Mas'ud) (may Allah be pleased with him) said: Allah Almighty will not look with mercy upon a man who has looked at the private parts of a woman and her daughter.

It is narrated from Abu Hani that the Messenger of Allah (peace and blessings be upon him) said: "If a man looks at the private part of a woman, her mother and her daughter are no longer lawful for him."

Yazid al-Rishk said: I asked Sa'id bin al-Musayyib: If a man commits fornication with his mother-in-law, what is the ruling? He said: The mother becomes forbidden, and the daughter remains lawful.
