Can he marry the daughter of his father’s wife?
Question

                A man got married to a woman who had a daughter when he got married to her, and he was blessed with children from her. Can the man’s son from another wife marry the daughter of this woman whom his father married?.
Praise be to Allah.
    There is nothing wrong with that, because there is no connection of blood between them, so she is a stranger (non-mahram) to him, and he is a stranger to her. So it is permissible for a person to marry the daughter of his father’s wife from another man, because Allaah says, after mentioning those to whom marriage is forbidden: “All others are lawful” [al-Nisa’ 4:24].
