﴿ إِلَّا ٱلَّذِينَ تَابُوا۟ مِنۢ بَعْدِ ذَٰلِكَ وَأَصْلَحُوا۟ فَإِنَّ ٱللَّهَ غَفُورٌۭ رَّحِيمٌۭ ﴾

“excepting [from this interdict] only those who afterwards repent and made amends: for, behold, God is much forgiving, a dispenser of grace.”

(Save those who afterward repent) after their slander (and make amends) between themselves and their Lord. ((For such) lo! Allah is Forgiving) He forgives whoever repents, (Merciful) He bestows mercy upon whoever dies repentant. This verse was revealed about 'Abdullah Ibn Ubayy and his host.
