Sura al-Nisāʾ 4:16

وَٱلَّذَانِ يَأْتِيَٰنِهَا مِنكُمْ فَـَٔاذُوهُمَا فَإِن تَابَا وَأَصْلَحَا فَأَعْرِضُوا۟ عَنْهُمَآ إِنَّ ٱللَّـهَ كَانَ تَوَّابًا رَّحِيمًا

wa-alladhāni yaʾtiyānihā minkum fa-ādhūhumā fa-in tābā wa-aṣlaḥā fa-aʿriḍū ʿanhumā inna allāha kāna tawwāban raḥīman

If two men among you are guilty of lewdness, punish them both. If they repent and amend, Leave them alone; for Allah is Oft-returning, Most Merciful.
