﴿ إِنَّ ٱلَّذِينَ يَرْمُونَ ٱلْمُحْصَنَٰتِ ٱلْغَٰفِلَٰتِ ٱلْمُؤْمِنَٰتِ لُعِنُوا۟ فِى ٱلدُّنْيَا وَٱلْءَاخِرَةِ وَلَهُمْ عَذَابٌ عَظِيمٌۭ ﴾

“[But,] verily, those who [falsely, and without repentance,] accuse chaste women who may have been unthinkingly careless but have remained true to their faith, shall be rejected [from God’s grace] in this world as well as in the life to come: and awesome suffering awaits them”
