Praise be to Allah.
Parents should give their children a good upbringing and take care of them so that they will be in a good state in both religious and worldly affairs.
If a child grows up disobedient and rebellious, then the parents must do more and try harder to guide him and make him righteous, by reminding him and advising him, showing patience towards him, praying for him, choosing good friends for him and choosing righteous acquaintances who can visit him, and advise him and befriend him.
