I am a practicing muslim. I am a privet tutor. I teach students at their home. I usually teach mathematics. I have a student of class 8. And in class 8's math text book there is chapter of interest( which is based on calculating riba, profit percentage etc.). Is it permissible for me to teach this chapter to my student? If not then how should i continue my privet tuition? Should I leave my students? And I have a plan of doing MBA( there I have to study accounting, finance etc.) Is studying MBA permissible?

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.

There is no religious objection to teaching what is related to bank interest, as the mere teaching of it does not necessitate the approval of usury or consent to it.

However, explain to the students the prohibition of usury and the Sharia's position on it.

Likewise, there is no objection to studying accounting or finance and other disciplines. Therefore, only studying them does not necessitate the approval of usury or consent to it.

Allah Knows Best.
