As I understand it, there is usually in the Islamic world a call to prayer 5 times a day, at which point all do so.
I’m curious about popular tourist spots, that are also small physically. If there is a tiny historic mosque, where participating in prayer would be a signature experience for a Muslim tourist. Could they have multiple prayer times, each for a new busload of tourists? Or is it only proper to have the 5 standard ones, and whoever gets there late gets to pray near the diesel fumes?
