Quran 2:53 — The Heifer (Al-Baqarah)

Recall that we gave Moses scripture and the statute book, that you may be guided.

[2:52] Still, we pardoned you thereafter that you may be appreciative.

[2:54] Recall that Moses said to his people, "O my people, you have wronged your souls by worshiping the calf. You must repent to your Creator. You shall kill your egos. This is better for you in the sight of your Creator." He did redeem you. He is the Redeemer, Most Merciful.
