Virtues and Merits of the Prophet (pbuh) and his Companions
Chapter: The signs of Prophethood in Islam
Narrated `Aisha:
The Prophet (ﷺ) in his fatal illness, called his daughter Fatima and told her a secret because of which she started weeping. Then he called her and told her another secret, and she started laughing. When I asked her about that, she replied, The Prophet (ﷺ) told me that he would die in his fatal illness, and so I wept, but then he secretly told me that from amongst his family, I would be the first to join him, and so I laughed."
