Surah Anam ayat 120 Tafsir Quran 6:120

﴿وَذَرُوا ظَاهِرَ الْإِثْمِ وَبَاطِنَهُ ۚ إِنَّ الَّذِينَ يَكْسِبُونَ الْإِثْمَ سَيُجْزَوْنَ بِمَا كَانُوا يَقْتَرِفُونَ﴾
[ الأنعام: 120]

6:120 And leave what is apparent of sin and what is concealed thereof. Indeed, those who earn [blame for] sin will be recompensed for that which they used to commit.

And forsake leave outward aspect of sin and its inward aspect that is what is overt of it and what is secret — it is said that ‘sin’ here means fornication or it is said any act of disobedience; surely those who earn sin shall be requited in the Hereafter for what they used to perpetrate what they used to earn.

And avoid the impious, the immoral and the sinful act whether it be apparent or real, committed openly or secretly or suggested secretly to the mind. Indeed those who commit themselves to an evil line of conduct shall be requited with what is commensurate with their evil deeds

وَذَرُواْ ظَـهِرَ الإِثْمِ وَبَاطِنَهُ ( Leave evil, open and secret... ) refers to all kinds of sins committed in public and secret.
Qatadah said that, وَذَرُواْ ظَـهِرَ الإِثْمِ وَبَاطِنَهُ ( Leave sin, open and secret... ) encompasses sins committed in public and secret, whether few or many.
In another statement, Allah said, قُلْ إِنَّمَا حَرَّمَ رَبِّيَ الْفَوَحِشَ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ ( Say: "(But ) the things that my Lord has indeed forbidden are Al-Fawahish ( evil sins ) whether committed openly or secretly.) 7:33 This is why Allah said, إِنَّ الَّذِينَ يَكْسِبُونَ الإِثْمَ سَيُجْزَوْنَ بِمَا كَانُواْ يَقْتَرِفُونَ ( Verily, those who commit sin will get due recompense for that which they used to commit. ) Whether the sins they committed were public or secret, Allah will compensate them for these sins.
Ibn Abi Hatim recorded that An-Nawwas bin Sam`an said, "I asked Allah's Messenger ﷺ about Al-Ithm.
He said,
«الْإِثمُ مَا حَاكَ فِي صَدْرِكَ وَكَرِهْتَ أَنْ يَطَّلِعَ النَّاسُ عَلَيْه»
( The sin is that which you find in your heart and you dislike that people become aware of it. )

( Forsake the outwardness of sin ) the adultery of the outward ( and the inwardness thereof ) secret adultery, i.e. taking lovers in secret. ( Lo! those who garner sin ) those who commit adultery ( will be awarded ) a lashing in this world and punishment in the Hereafter because of ( that which they have earned ) i.e. committing adultery.

Leave (O mankind, all kinds of) sin, open and secret. Verily, those who commit sin will get due recompense for that which they used to commit.
