Quran 2:66 — The Heifer (Al-Baqarah)

We set them up as an example for their generation, as well as subsequent generations, and an enlightenment for the righteous.

[2:65] You have known about those among you who desecrated the Sabbath. We said to them, "Be you as despicable as apes."

[2:67] Moses said to his people, "GOD commands you to sacrifice a heifer." They said, "Are you mocking us?" He said, "GOD forbid, that I should behave like the ignorant ones."
