The Family Of Imran - 3:16 "They who say: "Our Lord, we have believed, forgive us our sins and protect us from the torment of Hell"."
The believers avoid major sins and do not persist in sin:
The Family Of Imran/3:135 Those who, when they commit a sin or wrong themselves, remember Allah and ask forgiveness for their sins. Who can forgive sins except Allah? And they do not go on sinning knowingly.
وَالَّذ۪ينَ اِذَا فَعَلُوا فَاحِشَةً اَوْ ظَلَمُٓوا اَنْفُسَهُمْ ذَكَرُوا اللّٰهَ فَاسْتَغْفَرُوا لِذُنُوبِهِمْۖ وَمَنْ يَغْفِرُ الذُّنُوبَ اِلَّا اللّٰهُۖ وَلَمْ يُصِرُّوا عَلٰى مَا فَعَلُوا وَهُمْ يَعْلَمُونَ

The Prophets/21:87 "And ZanNun (i.e. Jonah, whose name has the letter ´Nun´ in it)... He left his post in protest. He thought that We could not control him. Finally, in the darkness (in the belly of the fish) he said, "There is no god but You. You are almighty. I have done wrong,"he pleaded."
وَذَا النُّونِ اِذْ ذَهَبَ مُغَاضِباً فَظَنَّ اَنْ لَنْ نَقْدِرَ عَلَيْهِ فَنَادٰى فِي الظُّلُمَاتِ اَنْ لَٓا اِلٰهَ اِلَّٓا اَنْتَ سُبْحَانَكَۗ اِنّ۪ي كُنْتُ مِنَ الظَّالِم۪ينَۚ

The Stories/28:15 "He entered the city while his people were unaware. He saw two men fighting there, one from his side (Hebrew) and the other from the enemy´s side (Egyptian). The man from his side asked him for help against his enemy. So Moses struck the other with a blow and finished him off. He said, "This is the work of Satan; he is an enemy, a clear misleader."
وَدَخَلَ الْمَد۪ينَةَ عَلٰى ح۪ينِ غَفْلَةٍ مِنْ اَهْلِهَا فَوَجَدَ ف۪يهَا رَجُلَيْنِ يَقْتَتِلَانِۘ هٰذَا مِنْ ش۪يعَتِه۪ وَهٰذَا مِنْ عَدُوِّه۪ۚ فَاسْتَغَاثَهُ الَّذ۪ي مِنْ ش۪يعَتِه۪ عَلَى الَّذ۪ي مِنْ عَدُوِّه۪ۙ فَوَكَزَهُ مُوسٰى فَقَضٰى عَلَيْهِۘ قَالَ هٰذَا مِنْ عَمَلِ الشَّيْطَانِۜ اِنَّهُ عَدُوٌّ مُضِلٌّ مُب۪ينٌ
The Stories/28:16 "My Lord,"he said, "I have wronged myself, forgive me."And He forgave him. For He is Forgiving, Merciful."

اَلَّذ۪ينَ يَجْتَنِبُونَ كَـبَٓائِرَ الْاِثْمِ وَالْفَوَاحِشَ اِلَّا اللَّمَمَۜ اِنَّ رَبَّكَ وَاسِعُ الْمَغْفِرَةِۜ هُوَ اَعْلَمُ بِكُمْ اِذْ اَنْشَاَكُمْ مِنَ الْاَرْضِ وَاِذْ اَنْتُمْ اَجِنَّةٌ ف۪ي بُطُونِ اُمَّهَاتِكُمْۚ فَلَا تُزَكُّٓوا اَنْفُسَكُمْۜ هُوَ اَعْلَمُ بِمَنِ اتَّقٰى۟
