Sexual morality and chastity

وَٱلَّـٰتِى يَأْتِينَ ٱلْفَـٰحِشَةَ مِن نِّسَآئِكُمْ فَٱسْتَشْهِدُوا۟ عَلَيْهِنَّ أَرْبَعَةً مِّنكُمْ ۖ فَإِن شَهِدُوا۟ فَأَمْسِكُوهُنَّ فِى ٱلْبُيُوتِ حَتَّىٰ يَتَوَفَّىٰهُنَّ ٱلْمَوْتُ أَوْ يَجْعَلَ ٱللَّهُ لَهُنَّ سَبِيلًا

Those who commit immorality [i.e., unlawful sexual intercourse] of your women - bring against them four [witnesses] from among you. And if they testify, confine them [i.e., the guilty women] to houses until death takes them or Allāh ordains for them [another] way.

فَمَنِ ٱبْتَغَىٰ وَرَآءَ ذَٰلِكَ فَأُو۟لَـٰٓئِكَ هُمُ ٱلْعَادُونَ

But whoever seeks beyond that, then those are the transgressors -

وَٱلَّذِينَ لَا يَدْعُونَ مَعَ ٱللَّهِ إِلَـٰهًا ءَاخَرَ وَلَا يَقْتُلُونَ ٱلنَّفْسَ ٱلَّتِى حَرَّمَ ٱللَّهُ إِلَّا بِٱلْحَقِّ وَلَا يَزْنُونَ ۚ وَمَن يَفْعَلْ ذَٰلِكَ يَلْقَ أَثَامًا

And those who do not invoke with Allāh another deity or kill the soul which Allāh has forbidden [to be killed], except by right, and do not commit unlawful sexual intercourse. And whoever should do that will meet a penalty.
