What is the best solution to my problem please help me please

I am a nurse but i dont have philippine and saudi license. I was hired in medical clinic in riyadh. The owner of the clinic knows that i dont have license and hes ok with that. He hired me and he was my kafil. Stated in my employment contract, i have probationary period of 3 months if i am unfit or i dont have license the 1st party has the right to remove at work. But he did not remove me. I worked there for more than 8 months. Now this clinic did not pay my 3 months salary so i stopped working and find another job. Now he sue me and the case was forwarded in ministry of justice because he said im a fake nurse. And he wants me to pay 20,000Sr. My hearing will be next month. Please help me what i will do?
