Is it mandatory to appear in court when you are summoned?

I have a bank case of AED 64000 for which I was caught from Airport upon my return from vacation on Oct 3rd. I was detained in Naif police station and next day they gave me bail by keeping my passport.

Now I have received a summons from court to appear before the prosecutor on Nov 5th. I'm really afraid if they will put me in jail again.

I also didn't go for negotiation with the bank as many of my friends advised me that there is no need for that as I will have to pay only a fine of AED 2000 for this. Is it true?

I feel very worried as the day is approaching. Please help urgently.
