And (remember) when Musa (Moses) said to his people: "O my people! Verily, you have wronged yourselves by worshipping the calf. So turn in repentance to your Creator and kill yourselves (the innocent kill the wrongdoers among you), that will be better for you with your Lord." Then He accepted your repentance. Truly, He is the One Who accepts repentance, the Most Merciful.
