I was watching a Turkish soap opera called Magnificent Century. A preacher in the series was saying that Jesus (PBUH) was more significant than Mohammed (PBUH). The Sultan ordered people to prove that the preacher was wrong and then kill him. But the Sultan's priests had failed to prove that twice already.
The series is made by Muslims and is entirely about Turkish Muslims. I do not understand the purpose of the debates shown.
Is it common in Islam to debate who is more significant?
