The fornicator does not marry except a ˹female˺ fornicator or polytheist, and none marries her except a fornicator or a polytheist, and that has been made unlawful to the believers.  

الزَّانِي لَا يَنْكِحُ إِلَّا زَانِيَةً أَوْ مُشْرِكَةً وَالزَّانِيَةُ لَا يَنْكِحُهَا إِلَّا زَانٍ أَوْ مُشْرِكٌ ۚ وَحُرِّمَ ذَٰلِكَ عَلَى الْمُؤْمِنِينَ  

And those who accuse chaste women and then do not produce four witnesses - lash them with eighty lashes and do not accept from them testimony ever after. And those are the defiantly disobedient,  

وَالَّذِينَ يَرْمُونَ الْمُحْصَنَاتِ ثُمَّ لَمْ يَأْتُوا بِأَرْبَعَةِ شُهَدَاءَ فَاجْلِدُوهُمْ ثَمَانِينَ جَلْدَةً وَلَا تَقْبَلُوا لَهُمْ شَهَادَةً أَبَدًا ۚ وَأُولَٰئِكَ هُمُ الْفَاسِقُونَ  

Except for those who repent thereafter and reform, for indeed, Allah is Forgiving and Merciful.  

إِلَّا الَّذِينَ تَابُوا مِنْ بَعْدِ ذَٰلِكَ وَأَصْلَحُوا فَإِنَّ اللَّهَ غَفُورٌ رَحِيمٌ
