4 Witnesses & Hadith

The Quran claims that in the case of a testimony to be believed in the case of adultery, the act must have four witness testimonies.

4:15 Those who commit adultery among your women, you must have four witnesses against them, from among you. If they do bear witness, then you shall keep such women in their homes until they die, or until GOD creates an exit for them.

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

24:4 Those who accuse married women of adultery, then fail to produce four witnesses, you shall whip them eighty lashes, and do not accept any testimony from them; they are wicked.

وَٱلَّذِينَ يَرْمُونَ ٱلْمُحْصَنَـٰتِ ثُمَّ لَمْ يَأْتُوا۟ بِأَرْبَعَةِ شُهَدَآءَ فَٱجْلِدُوهُمْ ثَمَـٰنِينَ جَلْدَةً وَلَا تَقْبَلُوا۟ لَهُمْ شَهَـٰدَةً أَبَدًا وَأُو۟لَـٰٓئِكَ هُمُ ٱلْفَـٰسِقُونَ
