Liability to pay compensation against resignation in a limited contract

Dear Ma’am,

My company is not paying our salaries for the last 90 days. The company is registered in RAK free zone.

I want to resign but the company is asking me to pay 45 days salary since my contract is limited.

I would like to inquire, why should an employee pay 45 days salary if the resignation is because of no salaries since the last 3 months.

Looking for your guidance.

Thank you best regards,

I. I.
