Quran 2:120 — The Heifer (Al-Baqarah)

Neither the Jews, nor the Christians, will accept you, unless you follow their religion. Say, "GOD's guidance is the true guidance." If you acquiesce to their wishes, despite the knowledge you have received, you will find no ally or supporter to help you against GOD.

[2:119] We have sent you with the truth as a bearer of good news, as well as a warner. You are not answerable for those who incur Hell.

[2:121] Those who received the scripture, and know it as it should be known, will believe in this. As for those who disbelieve, they are the losers.
