4:16
وَٱلَّذَانِيَأْتِيَٰنِهَامِنكُمْفََٔاذُوهُمَا ۖفَإِنتَابَاوَأَصْلَحَافَأَعْرِضُوا۟عَنْهُمَآ ۗإِنَّٱللَّهَكَانَتَوَّابًارَّحِيمًا١٦
wa-alladhāni yatiyānihā minkum faādhūhumā fa-in tābā wa-aṣlaḥā fa-aʿriḍū ʿanhumā inna l-laha kāna tawwāban raḥīman
And the two who commit it [i.e., unlawful sexual intercourse] among you - punish [i.e., dishonor] them both. But if they repent and correct themselves, leave them alone. Indeed, Allāh is ever Accepting of Repentance and Merciful.(16)
