Islam, the Official Religion
Although Islam is Dubai’s official religion, Dubai is pretty laid-back in enforcing its people towards Islamic rules and law. But there are still certain Islamic cultural traditions that everyone should obey if they want to avoid the risk of paying fines.
Such laws include wearing modest clothing (including men) while in public, no public display of affection (since it’s considered discourteous in Dubai), and don’t even try to engage in sexual intercourse in public areas even if it’s quiet and hidden public areas. If people are somehow confused about what is considered modest or not in terms of clothing, most places in Dubai have dress code info displayed at the entrance.
