﴿ وَلَوْلَا فَضْلُ ٱللَّهِ عَلَيْكُمْ وَرَحْمَتُهُۥ وَأَنَّ ٱللَّهَ تَوَّابٌ حَكِيمٌ ﴾

“AND WERE it not for God’s favour upon you, [O man,] and His grace, and that God is a wise acceptor of repentance...!”

(And had it not been for the grace of Allah and His mercy unto you) He would reveal who was lying of the two, (and that Allah is Clement) Allah forgives whoever repents, (Wise, (ye had been undone)) He decreed that this swearing and cursing takes place between the husband and his wife whom he accuses of adultery. This verse was revealed about 'Asim Ibn 'Adiyy al-Ansari who was afflicted with this.
