Addendum: A man married a woman and consummated the marriage, then after a month he learned that her mother had been breastfed by his mother. What is the ruling?

The Shaykh : The ruling is: what is the relationship if her mother was breastfed by his mother? She becomes his sister, and he becomes her maternal uncle. Consequently, there is no valid marriage between them. He must separate from her because she is not his wife. However, if she has given birth to children from him, the children are legitimate because the intercourse occurred under a misconception.
