Sir, my graduate admission requirements were to have DTE certified with experience. It was also said that the previous result and experience will be considered for selecting the students. I had good results but had no experience. So, I made a false experience certificate and got the admission. After that, I successfully completed my BscTE degree from university. After that I gained my msc degree and worked for few companies and earned for living. My question is can I use my bsc and Mac degree certificate for future job. Note that I am unemployed right now and all of my savings from job is halal or haram for me?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

Forging a certificate of experience is not permissible, so you have to repent from fraud and forgery, by regretting what you have done, and being determined not to repeat the same thing again in the future.

As regards working with the Bachelor's degree and Master's degree in the future, there is no harm in it and there is nothing wrong with the salary for this work if you perform it in the required manner.

Allah knows best.
