وَاِذْ قَالَ مُوْسٰی لِقَوْمِهٖ یٰقَوْمِ اِنَّكُمْ ظَلَمْتُمْ اَنْفُسَكُمْ بِاتِّخَاذِكُمُ الْعِجْلَ فَتُوْبُوْۤا اِلٰی بَارِىِٕكُمْ فَاقْتُلُوْۤا اَنْفُسَكُمْ ذٰلِكُمْ خَیْرٌ لَّكُمْ عِنْدَ بَارِىِٕكُمْ فَتَابَ عَلَیْكُمْ اِنَّهٗ هُوَ التَّوَّابُ الرَّحِیْمُ ۟

“And remember Moses said to his people: "O my people! Ye have indeed wronged yourselves by your worship of the calf: So turn (in repentance) to your Maker, and slay yourselves (the wrong-doers); that will be better for you in the sight of your Maker." Then He turned towards you (in forgiveness): For He is Oft-Returning, Most Merciful.”
