From Sahih Bukhari (Hadith 7370):
Narrated Aisha:Allah's Messenger (ﷺ) addressed the people, and after praising and glorifying Allah, he said, "What do you suggest me regarding those people who are abusing my wife? I have never known anything bad about her." The sub-narrator, `Urwa, said: When `Aisha was told of the slander, she said, "O Allah's Apostle! Will you allow me to go to my parents' home?" He allowed her and sent a slave along with her. An Ansari man said, "Subhanaka! It is not right for us to speak about this. Subhanaka! This is a great lie
