Verse 23

إِنَّ ٱلَّذِينَ يَرْمُونَ ٱلْمُحْصَنَـٰتِ ٱلْغَـٰفِلَـٰتِ ٱلْمُؤْمِنَـٰتِ لُعِنُوا۟ فِى ٱلدُّنْيَا وَٱلْـَٔاخِرَةِ وَلَهُمْ عَذَابٌ عَظِيمٌ

Those who summarily accuse the faithful chaste women, they are cursed in this world as well as the Hereafter and reserved for them is a tremendous suffering.
