Allah stated that the gooddoers are those who avoid major sins and immoral sins. They sometimes commit minor sins, but they will be forgiven these minor sins and covered from exposure, as Allah mentioned in another Ayah;

﴿إِن تَجْتَنِبُواْ كَبَآئِرَ مَا تُنهَوْنَ عَنْهُ نُكَفِّرْ عَنْكُمْ سَيِّئَـتِكُمْ وَنُدْخِلْكُمْ مُّدْخَلاً كَرِيماً ﴾

(If you avoid the great sins which you are forbidden to do, We shall expiate from you your (small) sins, and admit you to a Noble Entrance.)(4:31) Allah said here,

﴿الَّذِينَ يَجْتَنِبُونَ كَبَـئِرَ الإِثْمِ وَالْفَوَحِشَ إِلاَّ اللَّمَمَ﴾

(Those who avoid great sins and Al-Fawahish (immoral sins) except Al-Lamam), Al-Lamam means, small faults and minor errors. Imam Ahmad recorded that Ibn `Abbas said, "I have not seen anything that resembles Al-Lamam better than the Hadith that Abu Hurayrah narrated from the Prophet ,

«إِنَّ اللهَ تَعَالَى كَتَبَ عَلَى ابْنِ آدَمَ حَظَّهُ مِنَ الزِّنَا، أَدْرَكَ ذلِكَ لَا مَحَالَةَ، فَزِنَا الْعَيْنِ النَّظَرُ، وَزِنَا اللِّسَانِ النُّطْقُ، وَالنَّفْسُ تَتَمَنَّى وَتَشْتَهِي، وَالْفَرْجُ يُصِدِّقُ ذلِكَ أَوْ يُكَذِّبُه»

(Verily, Allah the Exalted has decreed for the Son of Adam his share of Zina and he will certainly earn his share. The Zina of the eye is by looking, the Zina of the tongue is by talking and the heart wishes and lusts, but the sexual organ either substantiates all this or not.)'' This Hadith is recorded in the Two Sahihs. Ibn Jarir recorded that Ibn Mas`ud said, "The eyes commit Zina by looking, the lips by kissing, the hands by transgressing, the feet by walking, and the sexual organ either materializes all of this or not. When one commits sexual intercourse, he will be someone who committed Zina. Otherwise, it is Al-Lamam.'' Masruq and Ash-Sha`bi also held the same view. `Abdur-Rahman bin Nafi`, who is also known as Ibn Lubabah At-Ta'ifi, said, "I asked Abu Hurayrah about Allah's statement,

﴿إِلاَّ اللَّمَمَ﴾

(except the Lamam), and he said, `It pertains to kissing, winking one's eye, looking and embracing. When the sexual organ meets the sexual organ in intercourse then Ghusl is obligatory, and that is Zina.''
