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." (Using translation from Bukhārī 3625)
أَنَّ رَسُولَ اللهِ ﷺ دَعَا فَاطِمَةَ ابْنَتَهُ فِي وَجَعِهِ الَّذِي تُوُفِّيَ فِيهِ فَسَارَّهَا بِشَيْءٍ فَبَكَتْ ثُمَّ دَعَاهَا فَسَارَّهَا فَضَحِكَتْ قَالَتْ فَسَأَلْتُهَا عَنْ ذَلِكَ فَقَالَتْ «أَخْبَرَنِي رَسُولُ اللهِ ﷺ أَنَّهُ يُقْبَضُ فِي وَجَعِهِ هَذَا فَبَكَيْتُ ثُمَّ أَخْبَرَنِي أَنِّي أَوَّلُ أَهْلِهِ لَحَاقًا بِهِ فَضَحِكَتْ»
