Ayesha reported,

During the illness in which he passed away, the Prophet ﷺ called his daughter Fatimah and whispered something to her, and she wept. Then he called her again and whispered to her, and she laughed.She said, "I asked her about that, and she said, 'The Prophet ﷺ whispered to me and informed me that he would die from the illness he was suffering, so I wept. Then he whispered to me again and informed me that I would be the first of his family to follow him, so I laughed.'"

عن عائشة قالت

دعا النبي ﷺ فاطمة ابنته في شكواه الذي قبض فيها، فسارها بشيء فبكت، ثم دعاها فسارها فضحكت قالت: فسألتها عن ذلك، فقالت: سارني النبي ﷺ فأخبرني أنه يقبض في وجعه الذي توفي فيه فبكيت، ثم سارني فأخبرني أني أول أهل بيته أتبعه فضحكت.
