Surah Al-Baqara Ayahs #55 Translated in English

And [recall] when We made an appointment with Moses for forty nights. Then you took [for worship] the calf after him [i.e., his departure], while you were wrongdoers.

Then We forgave you after that so perhaps you would be grateful.

And [recall] when We gave Moses the Scripture and criterion that perhaps you would be guided.

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.

And [recall] when you said, "O Moses, we will never believe you until we see Allāh outright"; so the thunderbolt took you while you were looking on.
