Asalaam aleykoum.Is "Probability" in mathematics haram? And is it haram to study? If it is haram, will a person be helping in sin if he for example registrate students in math-courses (If he for exampel works as an education administrator at school/university in the west) if he do not know how the students are going to use the knowledge, how they take it etc.? Will the person be contributing to sin by doing the ssiments (registrate students in math courses, sell books (mathematics) etc.? Note that the question is about if the assiments of this job is halal or haram, and not about the enviroment (if its mixed etc.) Please answer as soon as possible. Barak'Allahu feekom.

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

This question reflects taking matters to an extreme depth and investigating them in a dispraised manner.

There is no sane person who says that mathematics is forbidden. Mathematics, in general, is a useful science, and there is no harm in studying it, teaching it, and selling its books.

Many important theories are based on the laws of probability.

We do not know what is the Islamic prohibition that you see in it. If you imagine that this involves indulging in the Unseen, then this is a strange imagination, and it is not worth attempting to prove its falseness.

It is apparent that such questions stem from whispers. Therefore, we advise you to repel them and not pay any attention to them.

Allah knows best.
