by hitting or shouting at students?

I work as a teacher and sometimes I have to hit orshout at the
students, because all the teachers do that. I have tried to make
myself not do that, but it happened today. Is the fast invalidated by
hitting and shouting and getting angry? Do you advise me to give up
this profession because of what it leads to of lack of psychological
instability, and it is affecting my worship of Allah because Ifeel
guilty after hitting or shouting? Please note that I would do that
wereit not for my mother who may be upset if I give it up.
Praise be to Allaah.
Firstly:
Hitting and shouting are not things that break the fast, even if it is
done by way of aggression, so how about if the hitting and shouting
are done forthe purpose of discipline, teaching and directing?
Undoubtedly in that case it is clear that they do not break the fast.
Please see the answer to question number 106473 .
Secondly:
We advise you to remain in this job -- teaching -- because it is one
of the noblest and most important kinds of work, and it is essential
to pay attention to knowledge and teaching, and to make sacrifices for
the sake of reviving our schools and universities and taking them to
the highest levels and most sublime of goals. Try to overcome every
problem you face in your work with wisdom and deliberation, and
consult former teachers who haveexperience.
We ask Allah to guide andhelp us and you in this world and to grant us
success in the Hereafter.
And Allah knows best.
