The ruling on the children of a son from his father's slave woman

Question : Are the children of a son from his father's slave woman, the children of a father from his son's slave woman (according to the view that the marriage is valid), and the children of a mother from her son's slave male free or not?

Answer : We have previously stated that they follow the status of the mother in terms of freedom. If the mother is a slave woman, they are slaves; if she is free, they are free.
