Quran 2:136 — The Heifer (Al-Baqarah)

Say, "We believe in GOD, and in what was sent down to us, and in what was sent down to Abraham, Ismail, Isaac, Jacob, and the Patriarchs; and in what was given to Moses and Jesus, and all the prophets from their Lord. We make no distinction among any of them. To Him alone we are submitters."

[2:135] They said, "You have to be Jewish or Christian, to be guided." Say, "We follow the religion of Abraham—monotheism—he never was an idol worshiper."

[2:137] If they believe as you do, then they are guided. But if they turn away, then they are in opposition. GOD will spare you their opposition; He is the Hearer, the Omniscient.
