﴿ وَلَوْلَا فَضْلُ ٱللَّهِ عَلَيْكُمْ وَرَحْمَتُهُۥ فِى ٱلدُّنْيَا وَٱلْءَاخِرَةِ لَمَسَّكُمْ فِى مَآ أَفَضْتُمْ فِيهِ عَذَابٌ عَظِيمٌ ﴾

“And were it not for God’s favour upon you, [O men,] and His grace in this world and in the life to come, awesome suffering would indeed have afflicted you in result of all [the calumny] in which you indulge”

Then Allah revealed the following about those who did not slander 'A'ishah but talked about the slander: (Had it not been for the grace of Allah and His mercy unto you in the world and the Hereafter an awful doom had overtaken you) chastisement would have seized you in this worldly life and in the Hereafter (for that whereof you murmured) for the slanderous accusation which you repeated.
