There is no sin on those who believe and do good, righteous deeds for what they might have partaken (in their pre-Islamic past), provided (henceforth) they fear (the end of their previous creeds and misdeeds) and come to faith and do good, righteous deeds, then keep from disobedience to God in reverence for Him and piety and believe (more profoundly), then be more meticulous in obeying God in greater reverence for Him and piety and be devoted to doing good: God loves those who are devoted to doing good, aware that God is seeing them.
