Surah Al-Baqarah, verse 52

وَإِذْ فَرَقْنَا بِكُمُ ٱلْبَحْرَ فَأَنجَيْنَـٰكُمْ وَأَغْرَقْنَآ ءَالَ فِرْعَوْنَ وَأَنتُمْ تَنظُرُونَ ﴿٥٠﴾

And [recall] when We parted the sea for you and saved you and drowned the people of Pharaoh while you were looking on.

وَإِذْ وَٰعَدْنَا مُوسَىٰٓ أَرْبَعِينَ لَيْلَةًۭ ثُمَّ ٱتَّخَذْتُمُ ٱلْعِجْلَ مِنۢ بَعْدِهِۦ وَأَنتُمْ ظَـٰلِمُونَ ﴿٥١﴾

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.

وَإِذْ ءَاتَيْنَا مُوسَى ٱلْكِتَـٰبَ وَٱلْفُرْقَانَ لَعَلَّكُمْ تَهْتَدُونَ ﴿٥٣﴾

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

وَإِذْ قَالَ مُوسَىٰ لِقَوْمِهِۦ يَـٰقَوْمِ إِنَّكُمْ ظَلَمْتُمْ أَنفُسَكُم بِٱتِّخَاذِكُمُ ٱلْعِجْلَ فَتُوبُوٓا۟ إِلَىٰ بَارِئِكُمْ فَٱقْتُلُوٓا۟ أَنفُسَكُمْ ذَٰلِكُمْ خَيْرٌۭ لَّكُمْ عِندَ بَارِئِكُمْ فَتَابَ عَلَيْكُمْ ۚ إِنَّهُۥ هُوَ ٱلتَّوَّابُ ٱلرَّحِيمُ ﴿٥٤﴾

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.
