وَٱلَّٰتِى يَأْتِينَ ٱلْفَٰحِشَةَ مِن نِّسَآئِكُمْ فَٱسْتَشْهِدُوا۟ عَلَيْهِنَّ أَرْبَعَةً مِّنكُمْ فَإِن شَهِدُوا۟ فَأَمْسِكُوهُنَّ فِى ٱلْبُيُوتِ حَتَّىٰ يَتَوَفَّىٰهُنَّ ٱلْمَوْتُ أَوْ يَجْعَلَ ٱللَّهُ لَهُنَّ سَبِيلًا ١٥
15. Those who commit immorality [i.e., unlawful sexual intercourse] of your women - bring against them four [witnesses] from among you. And if they testify,169 confine them [i.e., the guilty women] to houses until death takes them or Allāh ordains for them [another] way.170
Notes
[169] The witnesses must swear to actually having seen the act taking place.
[170] The "other way" (i.e., penalty) was later revealed in 24:2, canceling the ruling in this verse.
