A'isha (RA) Reported Her Conversation With Fatima (RA), where she asked her:

What is that which Allah's Messenger (ﷺ) said to you secretly and you wept and then said to you something secretly and you laughed? Thereupon she said: He informed me secretly of his death and so I wept. He then again informed me secretly that I would be the first amongst the members of his family to follow him and so I laughed.
