Sahih al-Bukhari 3971 (Book 64, Hadith 187)

Narrated Masruq bin Al-Aida: Um Ruman, the mother of `Aisha said that while `Aisha and she were sitting, an Ansari woman came
and said, “May Allah harm such and-such a person!” Um Ruman said to her, What is the matter?” She
replied, “My son was amongst those who talked of the story (of the Slander).” Um Ruman said, “What
is that?” She said, “So-and-so….” and narrated the whole story. On that `Aisha said, “Did Allah’s
Apostle hear about that?” She replies, “yes.” `Aisha further said, “And Abu Bakr too?” She replied,
“Yes.” On that, `Aisha fell down fainting, and when she came to her senses, she had got fever with
rigors. I put her clothes over her and covered her. The Prophet (ﷺ) came and asked, “What is wrong with
this (lady)?” Um Ruman replied, “O Allah’s Messenger (ﷺ)! She (i.e. `Aisha) has got temperature with
rigors.” He said, “Perhaps it is because of the story that has been talked about?” She said, “Yes.”
`Aisha sat up and said, “By Allah, if I took an oath (that I am innocent), you would not believe me,
and if I said (that I am not innocent), you would not excuse me. My and your example is like that of
Jacob and his sons (as Jacob said ): ‘It is Allah (Alone) Whose Help can be sought against that you
assert.’ Um Ruman said, “The Prophet (ﷺ) then went out saying nothing. Then Allah declared her
innocence. On that, `Aisha said (to the Prophet), “I thank Allah only; thank neither anybody else nor
you.”
