What is the ruling on hitting female students who need literary or scientific guidance?

It is good for the instructor and teacher to be gentle and lenient with both children and adults. However, if the situation calls for a non-bruising chastisement or a light beating, that is permissible, because it is characteristic of the foolish to behave badly and disrespectfully. Thus, there is a need for severity and strength that will be more effective than gentleness and leniency.
