How to know if I have a travel ban in case of violating Covid-19 regulations?

I would like to ask whether it is safe for me to visit the UAE again or not. I visited Dubai with 90 days visa last time.

When I hung out with my friends, policemen came to us to check our IDs. I showed my passport because I was just a visitor and my local friends showed them their Emirates IDs.

Some of my friends who have an Emirates ID received a fine notice of violation of Covid-19 regulations by SMS the next day from the Dubai police which I didn't. This happened about 1.5 months before my departure.

I called Dubai police after the incident and the officer told me that it should have been ok if I hadn't received a fine paper ticket that day without checking my passport number.

When I went to Dubai airport, no one stopped me at customs and I left the country. I am worried if there is a possibility I might get arrested on arrival when I visit the UAE next time.

Your legal advice is much appreciated.
