Is it permissible for a father to prevent his children from speaking with their mother and maternal aunts as a protective measure, especially since the mother and maternal aunts propagate erroneous ideas that may negatively affect their upbringing?

It is not permissible for a father to completely prevent his children from speaking to their mother or their maternal aunts, as this leads them to disobey their mother and sever ties of kinship. If there is corruption on their part, then he should prevent the interaction that causes this corruption, while striving to safeguard the children and raise them upon religion and and good morals.
