Not all Muslim countries do though. All north african countries have a saturday/sunday weekend, except Egypt. and even in Egypt some companies make sure a subset of their employees work on their weekend because, well, most of their partners are working.
I think it could be reasonably inferred that when someone says "the world stops turning", it's being used metaphorically. Kind of like "stop the presses".
Incorrect. In Islamic countries, which are a part of this world, like Saudi Arabia and Oman have Thu-Fri weekend.
