And when those come to you who believe in Our verses, say, "Peace be upon you. Your Lord has decreed upon Himself mercy: that any of you who does wrong out of ignorance and then repents after that and corrects himself - indeed, He is Forgiving and Merciful."
When those who accept My signs that indicate the truth of what you have brought come to you, O Messenger, then reply to their greeting of peace in honour of them and tell them the good news of My mercy. I have gracefully made mercy obligatory on Myself. If anyone among you commits sin, out of ignorance and foolishness, and then repents from that sin and sets their actions right, then I will forgive them, for I am Forgiving and Compassionate to the servant who repents to Me.
