What do Islam say about competition in non-religious worldly matters?
To clarify, this has nothing to do with this question: Are competitions haram?
Basically, I'm asking, if two people compete between each other in non-religious worldly matter (and not afterlife), for instance if I compete my classmate and I about scores or marks in a subject (that can be islamic education) is it haram? Or if two people compete about who's gonna persuade the other, is it haram? Because this can result in non-islamic acts such as insults, aggression... And will cause one of them to loose along with it's implications. En plus, those are just worldly matters.
