And [recall] when Moses said to his people, "O my people, indeed you have wronged yourselves by your taking of the calf [for worship]. So repent to your Creator and kill yourselves [i.e., the guilty among you]. That is best for [all of] you in the sight of your Creator." Then He accepted your repentance; indeed, He is the Accepting of Repentance, the Merciful.

When Mūsā said to his people: “My people, you have wronged yourselves by your taking the calf (as God). So, turn in repentance to your Creator, and slay yourselves. That will be better for you in the sight of your Creator”. Then, He accepted your repentance. Indeed He is the Most-Relenting, the Very-Merciful.
