(Annisa) 4 : 15
وَاللَّاتِي يَأْتِينَ الْفَاحِشَةَ مِنْ نِسَائِكُمْ فَاسْتَشْهِدُوا عَلَيْهِنَّ أَرْبَعَةً مِنْكُمْ ۖ فَإِنْ شَهِدُوا فَأَمْسِكُوهُنَّ فِي الْبُيُوتِ حَتَّىٰ يَتَوَفَّاهُنَّ الْمَوْتُ أَوْ يَجْعَلَ اللَّهُ لَهُنَّ سَبِيلًا
And if any of your women are brought committing a sexual offense, then you bring four witnesses from among yourselves upon them; and if they witness, then confine them (women) in the houses until death comes to them or Lord Allah directs a way about them.
