Surah 2 : Ayah 54

وَإِذْ قَالَ مُوسَىٰ لِقَوْمِهِۦ يَـٰقَوْمِ إِنَّكُمْ ظَلَمْتُمْ أَنفُسَكُم بِٱتِّخَاذِكُمُ ٱلْعِجْلَ فَتُوبُوٓا۟ إِلَىٰ بَارِئِكُمْ فَٱقْتُلُوٓا۟ أَنفُسَكُمْ ذَٰلِكُمْ خَيْرٌ لَّكُمْ عِندَ بَارِئِكُمْ فَتَابَ عَلَيْكُمْ ۚ إِنَّهُۥ هُوَ ٱلتَّوَّابُ ٱلرَّحِيمُ

And [remember] when Moses said to his people, “O my people, you have wronged yourselves by taking the calf [for worship]. So repent to your Creator and kill yourselves [i.e., the guilty among you]; that is best for you with your Creator.” Then He accepted your repentance, for He is the Accepter of Repentance, the Most Merciful.

Concise Quran Commentary

Also, remember that Allah’s allowing you to ask His forgiveness for worshipping the calf, when Moses (peace be upon him) told you that you had wronged yourselves by taking the calf as a god and worshipping it, were from the blessings of Allah. Moses told you to ask for forgiveness and repent to your Creator by some of you killing others, because turning to Him in this way was better for you than persisting in disbelief, which would lead to an eternity in the fire of Hell. So, you did this with Allah’s approval, and He forgave you, for He is Forgiving and Merciful with His servants.
