Religious hostility as a possible motive

Did you expect Dubai to become a target in the current Iran conflict? I certainly did not. And neither, I suspect, did the residents of Dubai themselves.
When I heard about the explosions in the city, my first reaction was that these were caused by the interception of missiles that were overflying Dubai on their way to US bases in the region. Never did it occur to me that Iran would send drones to attack civilian targets in Dubai, specifically selecting those with the greatest chance of hurting foreign tourists and visitors.
