We are a group of teachers asking your eminence about our religious position regarding the issue of private teaching process, taking into account that we do not teach the same students who are in our school but rather from outside the school (from other schools or external students) and as it is clear that students are different levels. We take fees for that. So we would like to know your rational opinion, is it a fatwa or a precaution?
