Quran 2:54 — The Heifer (Al-Baqarah)

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.

[2:53] Recall that we gave Moses scripture and the statute book, that you may be guided.

[2:55] Recall that you said, "O Moses, we will not believe unless we see GOD, physically." Consequently, the lightning struck you, as you looked.
