Can the employer deduct unpaid invoices by the employee's customer from his EOSB?

Hi

I'm resigning from my current company. But I'm worried because there has been an incident regarding a payment from a customer some months ago.

The company is a leasing company. The incident involves a tenant who is working under a company that pays for his housing provided that all necessary docs are submitted to them.

One of the docs needed is Tawtheeq or the documented tenancy contract in AUH which has some errors/differences from his last year's Tawtheeq.

Due to that, the tenant's company refuses to pay our company the rent which is around 35000. My company is blaming me for this and they said that I should pay for the loss.

The tenant paid from his own pocket 20,000. So there is a difference of 15000.

Can they claim from me this amount once I resign?

Will I be obliged to pay it before they can cancel me?

Or have any grounds on filing a complaint against me?

What are the legal bearings of this if any?

I'm under Unlimited Contract started 10/01/21. It's my 1st contract with them but it is my 2nd job in the UAE.
