Sahih al-Bukhari 3715, 3716
Narrated `Aisha:
The Prophet (ﷺ) called his daughter Fatima during his illness in which he died, and told her a secret 
whereupon she wept. Then he called her again and told her a secret whereupon she laughed. When I 
asked her about that, she replied, "The Prophet (ﷺ) spoke to me in secret and informed me that he would 
die in the course of the illness during which he died, so I wept. He again spoke to me in secret and 
informed me that I would be the first of his family to follow him (after his death) and on that I 
laughed."
حَدَّثَنَا يَحْيَى بْنُ قَزَعَةَ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، عَنْ أَبِيهِ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ دَعَا النَّبِيُّ صلى الله عليه وسلم فَاطِمَةَ ابْنَتَهُ فِي شَكْوَاهُ الَّذِي قُبِضَ فِيهَا، فَسَارَّهَا بِشَىْءٍ فَبَكَتْ، ثُمَّ دَعَاهَا فَسَارَّهَا فَضَحِكَتْ، قَالَتْ فَسَأَلْتُهَا عَنْ ذَلِكَ‏.‏ فَقَالَتْ سَارَّنِي النَّبِيُّ صلى الله عليه وسلم فَأَخْبَرَنِي أَنَّهُ يُقْبَضُ فِي وَجَعِهِ الَّذِي تُوُفِّيَ فِيهِ فَبَكَيْتُ، ثُمَّ سَارَّنِي فَأَخْبَرَنِي أَنِّي أَوَّلُ أَهْلِ بَيْتِهِ أَتْبَعُهُ فَضَحِكْتُ‏.‏
