The ruling on the salary received from work related to a forged certificate

Question:
I am a young man who holds a legal degree, or an American high school diploma, certified by the Ministry of Education. However, one of my friends took the exam on my behalf. This certificate is certified for work in Saudi Arabia, not for study, but for work only. What is the ruling on the salary he received from the job? Is this salary related to the certificate, or to the work I perform?

Answer:
This is a great abomination that is not permissible. This is forgery and lying, and taking money without its right. You submitted a certificate for someone else, forged for someone else. This is not permissible and not lawful. Rather, it is obligatory for you to repent to Allah from that, and to quit this bad job, and to seek employment through other realistic means from you, such as saying that you did such and such, and did such and such in such and such, and that you are successful in your work, until you obtain the certificate from those who know your work and have advised you and seen your diligence in your tasks.
As for this forged certificate, do not submit it—do not submit it to people—and you must repent for what has passed. You must repent to Allah for what has passed. If you have performed the work entrusted to you, fulfilled its right, and did not betray it, but rather fulfilled its right and succeeded in it, then you are entitled to what was given for your work. However, you must repent for the forgery you submitted. You must repent to Allah from that.

Question: I mean, is there a need for it to be announced to the authorities?

Answer: No, but he must repent to Allah.

Question: He takes the salary he received, meaning, for example, he received a salary previously?

Answer: He must repent to Allah, and this is in exchange for his work.
