I understand that it is impermissible to hit my child if it leaves a mark. However, what is the Islamic ruling regarding a light smack if the child continues to be disobedient?
We always advise the parents to avoid hitting their children because of the big harm of insult on the soul and mind of the child.Hitting any one including your children is not permissible if it leaves a mark. There is a penalty (Diyah) to be paid to the child if the mark is reddish, and more penalty if the mark is blueish.
Parents should look for other ways to deal with their children's disobedience which should be away from insulting or violence.
'Wassalam.
