'A'isha reported that Allah's Messenger (ﷺ) called his daughter Fatima (during his last illness). He said. to her something secretly and she wept. He again said to her something secretly and she laughed. 'A'isha further reported that she said to Fatima:
What is that which Allah's Messenger (ﷺ) said to you secretly and you wept and then said to you something secretly and you laughed? Thereupon she said: He informed me secretly of his death and so I wept. He then again informed me secretly that I would be the first amongst the members of his family to follow him and so I laughed.

 دَعَا فَاطِمَةَ ابْنَتَهُ فَسَارَّهَا فَبَكَتْ ثُمَّ سَارَّهَا فَضَحِكَتْ فَقَالَتْ عَائِشَةُ فَقُلْتُ لِفَاطِمَةَ مَا
 هَذَا الَّذِي سَارَّكِ بِهِ رَسُولُ اللَّهِ صلى الله عليه وسلم فَبَكَيْتِ ثُمَّ سَارَّكِ فَضَحِكْتِ قَالَتْ سَارَّنِي
 فَأَخْبَرَنِي بِمَوْتِهِ فَبَكَيْتُ ثُمَّ سَارَّنِي فَأَخْبَرَنِي أَنِّي أَوَّلُ مَنْ يَتْبَعُهُ مِنْ أَهْلِهِ فَضَحِكْتُ ‏.‏
