Sahih Bukhari Volume 9, Book 93, Hadith Number 591.

Narrated By ‘Urwa bin Az-Zubair : Sa’id bin Al-Musaiyab, ‘Alqama bin Waqqas and ‘Ubaidullah bin ‘Abdullah regarding the narrating of the forged statement against ‘Aisha, the wife of the Prophet, when the slanderers said what they said and Allah revealed her innocence. ‘Aisha said, “But by Allah, I did not think that Allah, (to confirm my innocence), would reveal Divine Inspiration which would be recited, for I consider myself too unimportant to be talked about by Allah through Divine Inspiration revealed for recitation, but I hoped that Allah’s Apostle might have a dream in which Allah would reveal my innocence. So Allah revealed: ‘Verily! Those who spread the slander are a gang among you…’ (The ten Verses in Surat-an-Nur) (24.11-20)
