regarding probationary period and contract termination. Usually, there are provisions for terminating contract by either party.

The most important thing here is sincerity, and I hope the family problem you are mentioning is real. I read some of your past comments on some threads and I'm really having a second thought about your real intention.

Actually, it should have been a different story if you had not submitted a resignation letter but since you have already, my advice is, if you are still within the probationary period, submit a letter of termination for your contract or submit an irrevocable resignation stating your reasons. Then study the Qatar Labor Law as to what are the consequences of such actions. But do not abscond but wait 'til they accept your letter. MAke sure you have a receipt copy of your letter bearing the date it was pass and received by the company!
