A man forged his academic certificate and was employed on the basis of it. He has now repented to Allah. What is the ruling on his salary?

Question:
He says: Honorable Shaykh, may Allah grant you success. I am a young man who forged my academic certificate and was employed on the basis of it. I have now repented and turned to obedience. What is the ruling on my salary? May Allah grant you success.

Answer:
There is no doubt that this is a great sin. The Prophet (peace and blessings be upon him) said, "Whoever cheats us is not one of us." This is forbidden, and it carries a great sin. As for the job, that depends on your performance of the work. If you are performing the work as required, even if you do not have a certificate, and if you are doing the work as required and doing it well, then there is no harm in that, provided you repent to Allah for the cheating that occurred. However, if you are not skilled in the work, it is obligatory for you to withdraw from this cheating and study again, or seek another job other than this one. Yes.
