What can I do to protect my children from their father's bad manners, as he curses and insults them in front of others, making them want to become like him, despite my attempts to remind them of Allah and prayer?

A father's ill-treatment of his children is impermissible in Islamic law, leading to their hatred of him and their being affected by his bad character.

To protect the children, the mother should: Advise her husband and warn him of the consequences of his actions. Guide the children and prevent them from being influenced by what they hear from their father. Connect them with good company and enroll them in a Quran memorization center. Be patient and not rush the outcome. Read consultation books on parenting and the problems of youth and adolescents. Remind the children of filial piety, even if the father acts wrongly. Frequently supplicate to Allah to rectify the children and make them a comfort to her eyes.
