Quran Al-Ahzab 33:30
يَٰنِسَآءَ ٱلنَّبِيِّ مَن يَأۡتِ مِنكُنَّ بِفَٰحِشَةٖ مُّبَيِّنَةٖ يُضَٰعَفۡ لَهَا ٱلۡعَذَابُ ضِعۡفَيۡنِۚ وَكَانَ ذَٰلِكَ عَلَى ٱللَّهِ يَسِيرٗا ٣٠
Translation
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 Allāh, easy.
