Answer
Wa `alaykum As-Salamu waRahmatullahi wa Barakatuh.
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
1- What you are doing is prohibited as you are helping students to cheat in the exams.
2- What you are earning from this job is haram.
In his response to your question, Sheikh Ahmad Kutty, a senior lecturer and an Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states:
You don’t need a mufti to tell you that these students are cheating. They are committing a grave sin, and you are committing a double sin by encouraging them to cheat and making money out of it. The income you earn through this fraudulent work is pure filth.
The Prophet (peace be upon him) warned us against unlawful earnings: He said Allah does not hear prayers of such people. He teaches us this principle by citing the case of an individual who undertakes journey to perform Hajj and raises his hands in the sacred sites to Allah, calling out saying: My Lord! My Lord! “How would Allah answer his prayers when his food is earned through illegal ways, his clothes are from unlawful earnings, and such income also nurtures his entire body?” (Muslim)
Allah Almighty knows best.
