Dr. Monzer Kahf, a prominent economist and counselor states: Cheating is certainly Haram; it is immoral too. It is a sin that is punishable by God unless it is fairly punished in this life.

But when one works in their future career jobs they will be paid for what they give of work, if they supposedly give a good work, they deserve their pay, which is Halal and if one puts poor work in, then their income then will not be Halal as they will be earning what they didn’t work for. And if one’s certificate is obtained with cheating their performance will most likely be poor and their success in any career will be doubtful.”
