Jami` at-Tirmidhi: Book 49, Hadith 272

Narrated ‘Aishah: “I have not seen anyone closer in conduct, way, and manners to that of the Messenger of Allah in regards to standing and sitting, than Fatimah the daughter of the Messenger of Allah (ﷺ).” She said “Whenever she would enter upon the Prophet (ﷺ) he would stand to her and kiss her, and he would sit her in his sitting place. Whenever the Prophet (ﷺ) entered upon her she would stand from her seat, and kiss him and sit him in her sitting place. So when the Prophet (ﷺ) fell sick and Fatimah entered, she bent over and kissed him. Then she lifted her head and cried, then she bent over him and she lifted her head and laughed. So I said: ‘I used to think that this one was from the most intelligent of our women, but she is really just one of the women.’ So when the Prophet (ﷺ) died, I said to her: ‘Do you remember when you bent over the Prophet (ﷺ) and you lifted your head and cried, then you bent over him, then you lifted your head and laughed. What caused you to do that?’ She said: ‘Then, I would be the one who spreads the secrets. He (ﷺ) told me that he was to die from his illness, so I cried. Then he told me that I would be the quickest of his family to meet up with him. So that is when I laughed.'”
