Al-An'aam • EN-AL-JALALAYN
﴿ وَذَرُوا۟ ظَٰهِرَ ٱلْإِثْمِ وَبَاطِنَهُۥٓ ۚ إِنَّ ٱلَّذِينَ يَكْسِبُونَ ٱلْإِثْمَ سَيُجْزَوْنَ بِمَا كَانُوا۟ يَقْتَرِفُونَ ﴾
“But abstain from sinning, be it open or secret-for, behold, those who commit sins shall be requited for all that they have earned.”
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.
