The ruling on a father preventing his children from visiting their relatives out of fear that they will be influenced by their corrupt beliefs

Question:
Also, one of the brothers asks. He says: His wife is a monotheist, but her family are upon shirk (associating partners with Allah). They make vows to other than Allah, they slaughter for other than Allah, and they swear by other than Allah. Is it permissible for him to prevent his young children from visiting them, fearing that they will be influenced by corrupt beliefs? And is this considered severing family ties, or is this what is obligatory in their right?

Answer:
If they invite them to their creed and to what they are upon, and they corrupt their religion for them, then he prevents them from visiting relatives of this description, in order to preserve their creed, their religion, and their safety. So if he fears for them, he prevents them. And if he leaves them to visit, he goes with them and returns with them, acting as a guardian over them and following them. Yes.
