수라 33 Al-Ahzab (Those who took up arms), 아야 30

1. يَا نِسَاءَ النَّبِيِّ مَنْ يَأْتِ مِنْكُنَّ بِفَاحِشَةٍ مُبَيِّنَةٍ يُضَاعَفْ لَهَا الْعَذَابُ ضِعْفَيْنِ ۚ وَكَانَ ذَٰلِكَ عَلَى اللَّهِ يَسِيرًا

   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.

   33:30
