Sahih al-Bukhari, Book 61, Hadith 130 (In-Book) ⓘ

Narrated `Aisha: The Prophet 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 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."

حَدَّثَنِي 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 فِيهِ، 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.‏
