NOTE* This is not meant to be offensive, but b4 i believe the Jews were the top, chosen by GOD but they abused their gifts from GOD and were watseful so Muslim's were chosen. Techinally a long time ago Jewish,Muslim,and Christian people believed in the SAME religion but christians changed their holy book, the religions above got holy books ^ and now all the rules are kind of bent and the Muslim religion is the only true one unless u believe in the ACTUAL other religions that were sent from the skies
Less racist answer
There is no religion that is top, although most religions may contain a small population that believes this about their religion.
Certain religions, such as Islam and Christianity have central tenets that state their faith is the only correct path, but people interpret these tenets in many different ways.
