The teacher increasing the punishment for students in the school

Question : Shaykh, may Allah bless you. He says: Some teachers, especially the young teachers in the school, say that perhaps they are unjust in their judgment regarding the punishment; perhaps they increase the punishment sometimes, or perhaps they punish a student for something he does not deserve. This happens frequently. What is the ruling, and what should this teacher do?

Answer : Justice is obligatory in everything. .
It is not required of you to be harsh or to fight, except that you do not transgress. This applies when the injustice is due to hatred. And in the other verse, , this applies when what drives one to injustice is kinship, family ties, or the like. It is not permissible for a person to let love or kinship drive him to injustice, nor to let hatred or aversion drive him to injustice.
A person who is among a group must be just among them. A man must be just between his two wives, and just between his children, and likewise just between his students. But some students... all of them... if I wanted to do harm.
And he participates with another student who does little harm. So the act is the same, but perhaps he imposes the punishment on the first one and not the second, because the first one does much harm, even though their act is the same. In this case, while we permit it, it should be specified that this is the reason, so that nothing remains in people's minds. Yes.
