Verse 19

إِنَّ ٱلَّذِينَ يُحِبُّونَ أَن تَشِيعَ ٱلْفَـٰحِشَةُ فِى ٱلَّذِينَ ءَامَنُوا۟ لَهُمْ عَذَابٌ أَلِيمٌ فِى ٱلدُّنْيَا وَٱلْـَٔاخِرَةِ وَٱللَّهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ

Certainly, those who want vice to spread amongst the faithful, reserved for them is a most painful suffering in this world as well as the Hereafter. And God knows while you do not know.
