الآية رقم (15) - وَاللاَّتِي يَأْتِينَ الْفَاحِشَةَ مِن نِّسَآئِكُمْ فَاسْتَشْهِدُواْ عَلَيْهِنَّ أَرْبَعةً مِّنكُمْ فَإِن شَهِدُواْ فَأَمْسِكُوهُنَّ فِي الْبُيُوتِ حَتَّىَ يَتَوَفَّاهُنَّ الْمَوْتُ أَوْ يَجْعَلَ اللّهُ لَهُنَّ سَبِيلاً

(15) - {Those who commit unlawful sexual intercourse of your women - bring against them four [witnesses] from among you. And if they testify, confine the guilty women to houses until death takes them or Allah ordains for them [another] way.}

Allah (swt) says:

وَلاَ تَقْرَبُواْ الزِّنَى إِنَّهُ كَانَ فَاحِشَةً وَسَاء سَبِيلاً

{And do not approach unlawful sexual intercourse. Indeed, it is ever an immorality and is evil as a way.}  (Al-Isra: 32)

فَاسْتَشْهِدُواْ عَلَيْهِنَّ أَرْبَعةً مِّنكُمْ{bring against them four [witnesses] from among you}: Look at the seriousness of saving lineages and honors, that is why accusing falsely chaste women is a big sin. There has to be four people who witnessed them, in this case, families are not subject to any troubles because of the haters and mischief-makers who try to denigrating people. In fact, Islam is very keen not only on building the family through the marriage contract and its conditions, the right choice of the wife and the husband, but then, on preservation and maintenance of the marital relationship from being overwhelmed by accusations, especially in what is related to women. Islam emphasizes on this issue, and the greatest emphasis in testimony contained in the Holy Qur’an is related to women.
