And when Musa said to his people: O my people! you have surely been unjust to yourselves by taking the calf (for a god), therefore turn to your Creator (penitently), so kill your people, that is best for you with your Creator: so He turned to you (mercifully), for surely He is the Oft-returning (to mercy), the Merciful.

And We did not send any messenger but that he should be obeyed by Allah's permission; and had they, when they were unjust to themselves, come to you and asked forgiveness of Allah and the Messenger had (also) asked forgiveness for them, they would have found Allah Oft-returning (to mercy), Merciful.

But whoever repents after his iniquity and reforms (himself), then surely Allah will turn to him (mercifully); surely Allah is Forgiving, Merciful.
