Islam threatened Christianity because it mounted a rival revelatory claim

Evidence

What Christians now confronted was a religion that was similar to theirs but that challenged the primacy of their belief system. The God of Christianity is the same God of Abraham worshiped in Islam, but Christianity claims that God’s revelation in Jesus marked the end of revelation and of prophecy. Islam makes a similar claim but argues that Muhammad was the last prophet who received the final and correct Word of God. — Deepa Kumar, Islamophobia and the Politics of Empire, 64
