سورة Al-Baqarah ( The Cow ) - الآية 54

And [recall] when Moses said to his people, ‘O my people! You have indeed wronged yourselves by taking up the Calf [for worship]. Now turn penitently to your Maker, and slay [the guilty among] your folks. That will be better for you with your Maker.’ Then He turned to you clemently. Indeed, He is the All-clement, the All-merciful.
