Musnad Ahmad 1154:2

Yazid ibn Harun narrated to us, he said: Ibrahim ibn Sa'd informed us, he said: My father narrated to us, from 'Urwah ibn al-Zubayr, from 'Aishah, she said: When the Messenger of Allah (peace and blessings of Allah be upon him) became ill, he called his daughter Fatimah and whispered to her, so she wept. Then he whispered to her, and she laughed. I asked her about that, and she said: "As for when I wept, he informed me that he was going to die, so I wept. Then he informed me that I would be the first of his family to join him, so I laughed."
