وَٱلَّذَانِ يَأْتِيَٰنِهَا مِنكُمْ فَـَٔاذُوهُمَا ۖ فَإِن تَابَا وَأَصْلَحَا فَأَعْرِضُوا۟ عَنْهُمَآ ۗ إِنَّ ٱللَّهَ كَانَ تَوَّابًۭا رَّحِيمًا
And as for the two of you who are guilty thereof, punish them both. And if they repent and improve, then let them be. Lo! Allah is ever relenting, Merciful.
