يَٰنِسَآءَ ٱلنَّبِىِّ مَن يَأْتِ مِنكُنَّ بِفَٰحِشَةٍ مُّبَيِّنَةٍ يُضَٰعَفْ لَهَا ٱلْعَذَابُ ضِعْفَيْنِ ۚ وَكَانَ ذَٰلِكَ عَلَى ٱللَّهِ يَسِيرًا
English - Sahih International
O wives of the Prophet, whoever of you should commit a clear immorality - for her the punishment would be doubled two fold, and ever is that, for Allah, easy.
