Quran 2:121 — The Heifer (Al-Baqarah)

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.

[2:120] 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.

[2:122] O Children of Israel, remember My favor which I bestowed upon you, and that I blessed you more than any other people.
