Proof?
Quran 9:29 - "Fight those who believe not in Allah nor the Last Day, nor hold that forbidden which hath been forbidden by Allah and His Messenger, nor acknowledge the religion of Truth, (even if they are) of the People of the Book, until they pay the Jizya with willing submission, and feel themselves subdued."
"People of the Book" refers to Christians and Jews.
According to this verse, they are to be violently subjugated, with the sole justification being their religious status.
Verse 9:33 tells Muslims that Allah has instructed them to make Islam "superior over all religions." This chapter was one of the final "revelations" from Allah and it set in motion the tenacious military expansion, in which Muhammad's companions managed
to conquer two-thirds of the Christian world in the next 100 years. Islam is intended to dominate all other people and faiths.
9:33
It is He Who has sent His Messenger (Muhammad) with guidance and the religion of truth (Islam), to make it superior over all religions even though the Mushrikun (polytheists, pagans, idolaters, disbelievers in the Oneness of Allah) hate (it).
