It is in the introduction of book.
Say, you disbelievers! I do not worship what you worship, nor do you
worship what I worship.
Neither can I worship what you worship, nor can you worship what I worship.
I will not worship what you worship, nor will you worship what I worship.
I don't want to worship what you worship and neither do you want to worship
what I worship.
So my religion is for me and your religion is for you.
Quran - Surah Kafuron
