When Moses returned, he said to his people, "My people! You have hurt your own 'Selves' (by worshiping the calf (7:152)). Turn in repentance to your Maker and kill your slavish mentality. That will be best for you in the Sight of your Maker." Thereupon He accepted your repentance. Verily, He is the Acceptor of repentance, the Merciful.
