The prescribed punishment for fornication, the qadhf (false accusation) ḥadd, and related rulings.
These verses are grouped by theme as a starting point — not as standalone rulings. A verse takes on its full meaning only in context: the verses before and after, the occasion of revelation (asbāb al-nuzūl) and the explanation of the scholars. So read each verse in full via the tafsir, and consult a qualified scholar when in doubt.
ٱلزَّانِيَةُ وَٱلزَّانِى فَٱجْلِدُوا۟ كُلَّ وَٰحِدٍۢ مِّنْهُمَا مِا۟ئَةَ جَلْدَةٍۢ ۖ وَلَا تَأْخُذْكُم بِهِمَا رَأْفَةٌۭ فِى دِينِ ٱللَّهِ إِن كُنتُمْ تُؤْمِنُونَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْءَاخِرِ ۖ وَلْيَشْهَدْ عَذَابَهُمَا طَآئِفَةٌۭ مِّنَ ٱلْمُؤْمِنِينَ
A hundred lashes for the zānī and zāniya — no compassion in Allah's religion. Witnesses present.
وَلَا تَقْرَبُوا۟ ٱلزِّنَىٰٓ ۖ إِنَّهُۥ كَانَ فَٰحِشَةًۭ وَسَآءَ سَبِيلًۭا
Do not approach zinā — it is an abomination and an evil way.
وَٱلَّذِينَ يَرْمُونَ ٱلْمُحْصَنَٰتِ ثُمَّ لَمْ يَأْتُوا۟ بِأَرْبَعَةِ شُهَدَآءَ فَٱجْلِدُوهُمْ ثَمَٰنِينَ جَلْدَةًۭ وَلَا تَقْبَلُوا۟ لَهُمْ شَهَٰدَةً أَبَدًۭا ۚ وَأُو۟لَٰٓئِكَ هُمُ ٱلْفَٰسِقُونَ
Qadhf-ḥadd: eighty lashes for accusing chaste women without four witnesses; testimony no longer accepted.
وَٱلَّٰتِى يَأْتِينَ ٱلْفَٰحِشَةَ مِن نِّسَآئِكُمْ فَٱسْتَشْهِدُوا۟ عَلَيْهِنَّ أَرْبَعَةًۭ مِّنكُمْ ۖ فَإِن شَهِدُوا۟ فَأَمْسِكُوهُنَّ فِى ٱلْبُيُوتِ حَتَّىٰ يَتَوَفَّىٰهُنَّ ٱلْمَوْتُ أَوْ يَجْعَلَ ٱللَّهُ لَهُنَّ سَبِيلًۭا
Earlier ruling: women who committed zinā — confine in houses until death or Allah makes a way for them.
