Surat An-Noor (The Light) - النور

وَٱلَّذِينَ يَرْمُونَ أَزْوَٰجَهُمْ وَلَمْ يَكُن لَّهُمْ شُهَدَآءُ إِلَّآ أَنفُسُهُمْ فَشَهَٰدَةُ أَحَدِهِمْ أَرْبَعُ شَهَٰدَٰتٍۭ بِٱللَّهِ إِنَّهُۥ لَمِنَ ٱلصَّٰدِقِينَ ﴿٦﴾ وَٱلْخَٰمِسَةُ أَنَّ لَعْنَتَ ٱللَّهِ عَلَيْهِ إِن كَانَ مِنَ ٱلْكَٰذِبِينَ﴿٧﴾

And (as for) those who accuse their wives and have no witnesses except themselves, the evidence of one of these (should be taken) four times, bearing Allah to witness that he is most surely of the truthful ones. And the fifth (time) that the curse of Allah be on him if he is one of the liars.
