Quran 2:65 — The Heifer (Al-Baqarah)

وَلَقَد عَلِمتُمُ الَّذينَ اعتَدَوا مِنكُم فِى السَّبتِ فَقُلنا لَهُم كونوا قِرَدَةً خٰسِئينَ

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

[2:64] But you turned away thereafter, and if it were not for GOD's grace towards you and His mercy, you would have been doomed.

[2:66] We set them up as an example for their generation, as well as subsequent generations, and an enlightenment for the righteous.
