Surah An-Nur 24:23

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

Indeed, those who [falsely] accuse chaste, unaware and believing women are cursed in this world and the Hereafter; and they will have a great punishment

Translation: Saheeh International

Tafsir

Truly those who make accusations of fornication against honourably married chaste women who are unaware of indecent acts — since it would never occur to them to commit such acts — who believe in God and His Messenger shall be cursed in this world and the Hereafter; and there will be an awful chastisement for them
