Praise be to Allah.We asked our shaykh, Shaykh Muhammad ibn Saalih al-‘Uthaymeen, about a woman who says, my parents are kaafirs and my husband will not let the children see them. Does he have any right to do that?
He answered, may Allaah preserve him, as follows:
He does not have that right, but she should be tactful with him. It should be said to the husband that if there is no danger to the children’s religious commitment, he should not stop them (from seeing their grandparents). And he can be on the safe side by going with his children when they visit their grandparents.
