Sura al-Nūr 24:2

ٱلزَّانِيَةُ وَٱلزَّانِى فَٱجْلِدُوا۟ كُلَّ وَٰحِدٍ مِّنْهُمَا مِا۟ئَةَ جَلْدَةٍ وَلَا تَأْخُذْكُم بِهِمَا رَأْفَةٌ فِى دِينِ ٱللَّـهِ إِن كُنتُمْ تُؤْمِنُونَ بِٱللَّـهِ وَٱلْيَوْمِ ٱلْأَخِرِ وَلْيَشْهَدْ عَذَابَهُمَا طَآئِفَةٌ مِّنَ ٱلْمُؤْمِنِينَ

l-zāniyatu wa-l-zānī fa-ijlidū kulla wāḥidin minhumā miʾata jaldatin wa-lā takhudhkum bihimā raʾfatun fī dīni allāhi in kuntum tuʾminūna billāhi wa-l-yawmi l-akhiri wa-l-yashhad ʿadhābahumā ṭāʾifatun mina l-muʾminīna

The woman and the man guilty of adultery or fornication,- flog each of them with a hundred stripes: Let not compassion move you in their case, in a matter prescribed by Allah, if ye believe in Allah and the Last Day: and let a party of the Believers witness their punishment.

Sura al-Nūr 24:3

ٱلزَّانِى لَا يَنكِحُ إِلَّا زَانِيَةً أَوْ مُشْرِكَةً وَٱلزَّانِيَةُ لَا يَنكِحُهَآ إِلَّا زَانٍ أَوْ مُشْرِكٌ وَحُرِّمَ ذَٰلِكَ عَلَى ٱلْمُؤْمِنِينَ

al-zānī lā yankiḥu illā zāniyatan aw mushrikatan wa-l-zāniyatu lā yankiḥuhā illā zānin aw mushrikun wa-ḥurrima dhālika ʿalā l-muʾminīna

Let no man guilty of adultery or fornication marry and but a woman similarly guilty, or an Unbeliever: nor let any but such a man or an Unbeliever marry such a woman: to the Believers such a thing is forbidden.
