What are the best ways to guide and advise a Muslim man and his daughter, given that he is married to a foreign woman and has a daughter with her who, in turn, married a foreign man and gave birth to a child, considering that we will be questioned about our children and how we raised them?

The marriage of a Muslim man to chaste women of the People of the Book, though permissible, is nowadays a source of calamities due to its severe negative consequences for the husband, children, and family. The children's personalities, especially the daughters, are affected by the non-Muslim mother's creed, behavior, and customs.

In the case mentioned, an immediate separation between the Muslim daughter and the European disbelieving husband is imperative, because, by scholarly consensus, it is not permissible for a Muslim woman to be married to a disbeliever, and she is not allowed to enable him to have relations with her. The child follows her in religion and lineage.
