Quran 24:4 An-Nur, ayah 4 of 64

وَٱلَّذِينَ يَرْمُونَ ٱلْمُحْصَنَـٰتِ ثُمَّ لَمْ يَأْتُوا۟ بِأَرْبَعَةِ شُهَدَآءَ فَٱجْلِدُوهُمْ ثَمَـٰنِينَ جَلْدَةً وَلَا تَقْبَلُوا۟ لَهُمْ شَهَـٰدَةً أَبَدًا ۚ وَأُو۟لَـٰٓئِكَ هُمُ ٱلْفَـٰسِقُونَ ۝٤

24:4 And those who accuse honourable women but bring not four witnesses, scourge them (with) eighty stripes and never (afterward) accept their testimony - They indeed are evil-doers -
