Al-An'aam 6:54

When those who believe in Our verses come to you, say, “Peace be upon you. Your Lord has decreed mercy upon Himself; whoever among you commits a sin out of ignorance then repents afterwards and mends his ways, then Allah is indeed All-Forgiving, Most Merciful.”

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."

54. When those who believe in Our Ayât (proofs, evidence, verses, lessons, signs, revelations, etc.) come to you, say: "Salâmun ‘Alaikum" (peace be on you); your Lord has written (prescribed) Mercy for Himself, so that if any of you does evil in ignorance, and thereafter repents and does righteous good deeds (by obeying Allâh), then surely, He is Oft-Forgiving, Most Merciful.

And when those who believe in Our revelations come unto thee, say: Peace be unto you! Your Lord hath prescribed for Himself mercy, that whoso of you doeth evil through ignorance and repenteth afterward thereof and doeth right, (for him) lo! He is Forgiving, Merciful.
