Is it permissible for one who obtained a certificate through cheating to take a job and work with it?

Question:
This person is asking: If a person obtained a certificate through cheating, is it permissible for him to take a job with it and work with it?

Answer:
We say that cheating is forbidden; cheating is forbidden. And whoever cheats must repent to Allah the Exalted. As for the job itself, if you perform it as required, performing the work as it should be done, some people perform the work even though they do not have a certificate. The discussion is about performing the work and doing it well. So if you perform the work as required, that is what is required of you, and you clear your conscience, along with repenting from the cheating that occurred. Yes.
But if you do not perform the work, even if you have a valid certificate with no cheating in it, you have a certificate with no cheating, but you do not perform the work, this is forbidden for you.
