Quran 5:74 — The Feast (Al-Ma'edah)

Would they not repent to GOD, and ask His forgiveness? GOD is Forgiver, Most Merciful.

[5:73] Pagans indeed are those who say that GOD is a third of a trinity. There is no god except the one god. Unless they refrain from saying this, those who disbelieve among them will incur a painful retribution.

[5:75] The Messiah, son of Mary, is no more than a messenger like the messengers before him, and his mother was a saint. Both of them used to eat the food. Note how we explain the revelations for them, and note how they still deviate!
