﴿ يَٰنِسَآءَ ٱلنَّبِىِّ مَن يَأْتِ مِنكُنَّ بِفَٰحِشَةٍۢ مُّبَيِّنَةٍۢ يُضَٰعَفْ لَهَا ٱلْعَذَابُ ضِعْفَيْنِ ۚ وَكَانَ ذَٰلِكَ عَلَى ٱللَّهِ يَسِيرًۭا ﴾

“O wives of the Prophet! If any of you were to become guilty of manifestly immoral conduct, double [that of other sinners] would be her suffering [in the hereafter]: for that is indeed easy for God.”

(O ye wives of the Prophet! Whosoever of you committeth manifest lewdness) plain adultery with witnesses to testify against you, (the punishment for her will be doubled) flogging and stoning, (and that) punishment (is easy for Allah.
