Is money earned from contributing to the training of postgraduate students who will work in usurious banks permissible or forbidden, and how can one dispose of this money if it is forbidden?

It is not permissible to teach students accounting systems for the purpose of working in usurious banks, nor to assist them in that; due to the Almighty's saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression."
